Where should I purchase a BiPap ASV?

My 16-year-old ASV machine died a few days ago. Thankfully, I have a backup. But it's time to replace it. My insurance is terrible and I may end up just paying cash myself.

I was surprised to find that cpap.com doesn't carry any ASV machines. Do any of you have any experience with other online sellers? Second Wind has a couple of used machines for sale. Also, what brand(s) do you prefer? Any I should avoid? I've been using a Respironics and they're not selling in the US at the moment.

Thank you,
Tony

I wouldn't be afraid to buy from secondwindcpap.com.

There is currently only one brand I would consider, Resmed.
Respironics shut down their US operation after their massive recall.
I would only use something that works with OSCAR.
Do you happen to use nocturnal Oxygen like I do? If so you will want the Aircurve 10 ASV, not the Aircurve 11 ASV which is a newer version. The 11 does not yet have an available Climate line hose with injection port.
If you don't use O2 there are still many pros and cons on the newer 11 machines. My wife uses an Airsense 11 so I have experience with both models and depending on the day I flip flop on which model I would prefer.
