If you decide to go for the new machine, you could keep the other one as a spair or use it for travel.
Best of luck to you on your decision and WELCOME! to the forum.!
I am sure your not going to keep the older one
The DMEs will Referbe it and sell it on
Enjoy the New Machine
All of the S9 VPAP machines and Philips Respironics PRS1 BiPAP machines are "good" in terms of full data collection.
The S9 VPAP auto is an excellent machine as far as I can tell. I haven't used one, but it seems many people find it feels "gentler" than the PRS1 models.
In the USA, A CPAP machine is usually "rent to own" with insurance. It's usually yours after 3-13 months. There may be a small number of exceptions, but it's rare.
All S9 machines will work with the optional heated hose. If you buy it without the hose bundled into the original purchase, you can upgrade later for the price of an expensive new heated hose.
You absolutely want the heated humidifier no matter which hose you get.
Some PRS1 machines will work with a heated hose, some won't.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
