I would like to buy a Resmed S8 Vantgage. My S7 I have used for 2. 5 yrs has not helped & ins. won't pay for one.

Does anybody have a Resmed S8vantage auto for sale? My stubborn sleep Dr. won't give me a prescription for one. I have been using a Resmed S7 for 2.5yrs., but my air pressure levels have changed & I can't afford to keep getting sleep studies done.
