You also had a prescription for those right? That's what I was referring to. If you get ahold of a machine without a doctor's permission slip, buying supplies is a bit more challenging.

Amazon won't sell you full mask sets, you have to buy the frame/cushion/headgear/tubing separately and put it together yourself. Usully at a very inflated markup.. recently had to pay $100 for a replacement frame after one of the headgear hooks snapped off of my F10.

Other CPAP companies online won't even talk to you without a prescription on file.
