Hello, I just found this thread looking for sites that sell CPAP machines. I have a CPAP machine that has never been used. This machine is a REMstar Auto C-Flex CPAP Machine. It comes with a travel case, all hoses, filters, instructions, and manuals.
I also have a FlexiFit HC432 Full Face CPAP Mask with Headgear - Small, never used still in box.
I have an excellent seller rating on ebay, if you advance search for lawoman68, you will be able to see my feedback.
If you are interested, I have pictures if you would like me to email them.
