cpap.com is a stand up place too. I have personally had to return a new machine (2 months old) to them due to warranty issues. It was a relatively painless procedure.
They only deal in new machines....no used or refurbished stuff.
Each place of business has their own unique place in the sale of cpap stuff.
And yes...the P10 is a hot seller in the nasal pillow department. It's about as next to nothing as anything currently out there.
Watch for my upcoming review (Bleep/DreamPort) on a new mask slated for release in a couple or three weeks. It's next to nothing too.

Review to be posted in a day or so...just needs a little more polish to it. I have been so busy haven't had quite enough time to check for typos and make sure my thoughts are conveyed in words like I am really thinking them.
I may have to RISE but I refuse to SHINE.
