Well, my CPAP machine is already relatively portable, but I don't have anywhere to nap at work, except in my car, which doesn't have an AC outlet (also, I'd like to start biking to work, so I don't want to wed myself to the car). I share a room with several other people, so I would need somewhere else to nap.

On an unrelated note: May I suggest getting a second travel CPAP even if you're not going to nap at the office?

You can use it for travel and vacations, but the best reason to have one is as a backup. Trust me when I say that you don't want to wait a month for a replacement when your existing CPAP fails (and it WILL fail).

Also, it's worth noting that many travel CPAPs have 12-volt car lighter adapters so you can run it off of your car's battery. So maybe you could use it to nap in your car?

Thanks for the suggestions. I'll definitely look into it.

My dad had a top of the line cpap that my mother just threw out.

Prior to that I had found a site that specialized in used cpaps and they were going to buy it (apparently they had so much inventory they wanted to wait to make an offer on it).

You can probably source a good used one through respiratory therapists either privately or at a hospital. When someone passes away these are typically thrown out. (After a certain amount of time they don't get returned to medicare or something like that.)

secondwindcpap.com is where I've gotten my last couple of units from.
