MIne is the Cadillac of CPAP's- $1100.00
Worth every penny. However, maintaining one is like owning another car- masks, straps, hoses, filters, all kinds of crap.
You can hack owning one on the cheap- do the sleep study, get the pressure settings, buy a used one off CL and then program it yourself. YOu only need the pressure settings from the study.
Beware- many of the ones on CL are used ones, with many hours on 'em and people are just upgrading. Every 5 years insurance co authorizes a new one. Make sure you buy one from someone who bought it but hated it. That happens a lot, too. No use and it's virtually 1/2 off.
