I know I am late on this but thought I would post anyway
My DH has CPAP and we bought his for about $1300 if I remember correctly. He had 2 seperate sleep tests which he had to stay overnight with all the old farts lol
The machine he has is automated and has the humidifier so it adjusts the air pressure to whatever he needs. We had a problem with the machine the other month and had to return it to the shop, but after about 2 years, it was still covered under warranty. Obviousbly the machine makes a little noise, but no more than say a computer left running in your room. And it is not what I would call romantic lol but you gotta do what you gotta do.
Honestly it is money well spent. Your DH will be able to breathe at night and will have so much more energy during the day and it will stop the snoring, win win win.
It is a lot of money to lay out up front. You can claim money back on medical expenses through tax, if you spend over a certain amount, you might want to look into it, The sleep tests didn't cost us any money, that was all covered by medicare.
