ebay and craigslist has thousands of oxygen concentrators for sale from the folks that have passed. We end up owning the machine after 13 months rental through medicare. I bought an invacare backup off craigslist for a couple hundred dollars almost brand new as a back up to the one Medicare covers for my mom in case it breaks down or she needs 2 since she is a mouth breather.
