online shopping

hi, i am on expanded medicaid but will be switching to an aca plan soon and the shortly after medicare. i just found out i need a apap machine. i really dont want to deal with all the insurance changes and possible compliance issues due to my erratic sleep schedule. i was considering just purchasing the machine outright. can anyone recommend an online retailer that is trustworthy. there are a few that were very cheap and had the same websites with different names that seemed too good to be true!i have decided on a resmed card to cloud 10 machine.........(to the person replying to every comment no i am not interested in a bleep mask!!!!! )
