I have always wondered how much it would cost to buy a cpap machine. My brother used to have lung problems when he was little, and he used to have to go to sleep with one of these. I wish that I would have asked my parents how much it cost. I think that I have sleep apnea, and am not sure if I'll have to get one in the near future.http://www.cornermedical.com/product-category/cpap-machines/
