Which machine is the best option

[Sparky223]

I have very little funds to spare so I am looking at the used ones between $100-$150 range.

[houstonrockets83]

no offence, I wouldn't trust craigs list for that, Ive sold 5 or 6 machines on here and I can prob work with you and get you a decent machine for $150, if your interested that is, if not sorry to bother you

The S9 Elite (3rd one top line) looks decent - see if you can find out the blower hours.

I have had great luck buying and selling on craigslist...you must be careful and meet in a public place...like a fast food restaurant where you can plug the unit in.

Sparky,

If it's possible to work with houstonrockets83, that's great.

But if you want to buy off your local Craigs list (with all the usual CL caveats) then here are the machines on your link that I would be looking at if I were you. I've listed the machines in from cheapest to most expensive.

https://denver.craigslist.org/hab/4987430331.html ($150) The machine is described as a PR System One Pro. It is clearly a Series 50 System One, so it's one generation older than the current PR machines, but it is a nice machine. The System One Pro records full efficacy data. The picture of the machine is not clear enough to make sure that it is indeed a Pro instead of a Plus. Before buying this model, you must see the model and turn it over to check the model number. If it says something like DS450, it's the Pro and you're good to go. If it says something like DS250, it's the Plus and you don't want it. If it says something like DS150, it's the model that's even worse than the Plus and you really don't want it.

http://fortcollins.craigslist.org/hab/4975907412.html ($150) The machine is described as a "CPAP breathing machine." The picture clearly indicates that it is a PR System One Series 50 PAP of some sort. But here again, without knowing the exact model number, it's impossible to tell whether this is a good buy or a bad buy. And the only way to tell (for sure) which model this machine is being sold is to see the machine in person and turn it over to look at it's model number. If

• Model number = DS150, the machine is crap and you don't want it.
• Model number = DS250, the machine records no efficacy data and you don't want it.
• Model number = DS450, the machine is a PR System One Pro, which is a good, full efficacy data machine and $150 is a reasonable price.
• Model number = DS550, the machine is a PR System One APAP, which is a good, full efficacy data machine and $150 is a reasonable price.

http://cosprings.craigslist.org/hab/4957577212.html ($175) The machine is described as a PR CPAP machine. Judging from the picture, it looks like a Series 50 machine, although it's harder to tell with this one than the previous one and it might just be a Series 60 machine. Same comments apply, however. Until you see the machine in person and flip it over to figure out exactly which model is being sold, it's impossible to tell if this is a decent price for a good machine or a bad price for a bad machine. If

• Model number = DS150, the machine is crap and you don't want it.
• Model number = DS250 or DS260, the machine records no efficacy data and you don't want it.
• Model number = DS450 or DS460, the machine is a PR System One Pro, which is a good, full efficacy data machine and $175 is a reasonable price.
• Model number = DS550 or DS560, the machine is a PR System One APAP, which is a good, full efficacy data machine and $175 is a reasonable price.

https://denver.craigslist.org/hab/4972835173.html ($250) The machine is described as an S9 Elite, which is a full data fixed pressure machine. It's now one generation older than the current Resmed machines, but it is a nice machine. It may be a bit over priced. And the picture of the machine is not quite clear enough to make sure that it is indeed an Elite instead of the similar looking Escape, which does not record any useful data. Before buying this machine I would want to see the machine in person and make sure that it says Elite instead of Escape on the top of the machine right by the ON/OFF button.

https://denver.craigslist.org/hab/4948413098.html ($300) The machine is described as a CPAP, but judging from the the picture of the machine itself, it looks like this one is actually a Resmed S9 AutoSet. Which was the top of the line Resmed model until a few months ago when the new AirSense 10's came out. The machine is probably a bit over priced. Before buying the machine, I would want to see it in person just to confirm that it is indeed an S9 AutoSet. Again, whether spending the extra $150 to get an APAP is a decision that only you can make. Before buying this machine I would want to see the machine in person and make sure that it says AutoSet instead of Auto Escape on the top of the machine right by the ON/OFF button.

https://denver.craigslist.org/hab/4952861781.html ($350) The machine is described as a PR System One APAP. It's a Series 50 System One and it's over priced in my opinion since this model was replaced by the Series 60 machines about 2 or 3 years ago. The picture is not clear enough to tell if the machine really is the APAP that's being advertised. Again, the only way to tell for sure is it see the machine in person and turn it over to look at the model number. It should say something like DS550 for the model number. While it's nice to have the capacity of an APAP, only you can decide if an APAP is worth 200 extra bucks.

https://denver.craigslist.org/hab/4939273769.html ($350) The machine is described as a Resmed S9 CPAP. Neither of the pictures is clear enough to determine the actual model of the machine. If it's an S9 Escape, it's vastly over priced. If it's an S9 Escape Auto, it's still vastly over priced. If it's an S9 Elite or an S9 AutoSet, it's somewhat over priced.

https://denver.craigslist.org/hab/4927796163.html ($400 or "best offer") The machine is described as a "BiPAP". From the looks of the machine, it is a PR System One Series 60 BiPAP Pro or a PR System One Series 60 BiPAP Auto. It is the current generation of BiPAPs made by PR, and $400 is less than half of what you would pay for this machine brand new from a place like our host. The seller says they've owned the machine for only two months, which means that it would be very important to establish that they actually own the machine outright. Many insurance companies buy the blower unit (the expensive part) on a "rent-to-own" basis, and if seller signed a rent-to-own agreement, then they probably don't actually own the machine yet. This machine is a bit more than you technically need if you're just looking for a CPAP, but it would have CPAP mode and some people do find bilevel machines more comfortable to use than CPAP/APAP machines. It's not at all clear whether an offer of $150 would be acceptable to the seller.

Before buying any of these machines from Craigslist, I would insist on meeting the seller in public and I would require the seller to bring the actual machine to the meeting and let you physically handle it. And I would make it clear when I set the meeting up that I will ONLY be buying the machine if the model number is completely acceptable to me and the machine meets my satisfaction when I get to inspect it in person. In addition to checking out the model number, it would also be worth while to insist on plugging the machine in and getting into the clinical menu to check the blower hours. The blower hours is kind of like a CPAP odometer: They cannot be reset and they give you an idea of how much the machine has actually been used. To put this in perspective:

• If a person uses a CPAP for 5.5 hours every night for a year, that's equal to about 2000 blower hours per year.
• If a person uses a CPAP for 8.2 hours every night for a year, that's equal to about 3000 blower hours per year.

And most CPAP manufacturers recommend replacing the machine every five years or so---in other words, you can very loosely think of this as the manufacturers think that the machine probably needs to be replaced before the total number of blower hours is somewhere on the high side of 20,000.

All the other machines listed on the Craigslist link you posted are very old---as in at least 6 or more years old and many of them appear to be in the 10-15 year old range. The older machines are badly outmoded at this point. And many of them are vastly over priced. None of these older machines are compatible with the SleepyHead software that we talk about so much around here. Even if they do record efficacy data, the data is recorded on an old, proprietary data card that requires a special card reader (which is impossible to find) and specialized software (which is not so hard to find) in order to be able to really track your data.

I have had great luck buying and selling on craigslist...you must be careful and meet in a public place...like a fast food restaurant where you can plug the unit in.

I like starbucks! they've got outlets scattered all over the place for the campers... and there's usually a crowd. and you can get some mediocre coffee.

craigslist isn't for someone that doesn't know anything about the machines though.

[houstonrockets83]

I only said that because the high amount of craigslist related crimes that happen in houston, not too long back a young man that was working on his phd was shot and killed over an iphone sell when he was robbed

[Sparky223]

houstonrockets made me a deal on one of these. Just need to find the tank for the humidifier.

AH, I wasn't sure if he meant he didn't have a humidifier, or just the chamber.
