That said, I encourage you to save up your money and get a cleaned, sanitized, known-to-be-working unit from Supplier #2. They have S9 Autosets for $379. For slightly more you can get a brand new one (599). Their sales page is long but it can be narrowed down by hitting Ctrl and F then entering in the name of the machine. Like "autoset" or "DS560" (Phillips' machine).
You have had sleep apnea for a while. Do not make the mistake of getting a machine that won't work for you or one that is not data capable just because you just got the diagnosis. Sit back. Breathe. Save up some money. Ask about masks. Do your research. Money is tight so don't toss it at the first machine to look at you and wink.
