I don't know your insurance situation, but a new S9 Elite or AutoSet has some LARGE advantages over your S8 machine. It might be a good way to convince your insurance to buy a new one.
Or buy a new one online or watch your local craigslist. I just got an S9 AutoSet for $250 from a local seller, but I did have to watch the ads for 6 months or so to find a price that goo.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
I used the kit yesterday, let it dry for a day, and now all the buttons work. Easily. It was fairly easy to do, though if you're not terribly nearsighted you might want some kind of magnifier. The swabs are kind of odd to work with, and I don't think that I was able to put on a really light coat of the stuff, as directed, but it seems to work fine. We'll see how long it lasts.
I didn't skip a night of CPAP, though. I got the machine into the on state some days ago, and I've been plugging and unplugging it to turn it on and off, so I didn't need the keyboard last night. I haven't skipped a night since I got the thing. I even use it for naps.
If I thought that a new CPAP would do for me what beer or a new car does for people in the commercials, it wouldn't be out of the question to go and buy one out of pocket. But I'm skeptical. For now, I'll settle for having only two yellow lines in the middle of the road when I'm driving and needing fewer naps.
I don't really get into the data that much, though I do check the apnea index, etc. from time to time. Generally, the machine works fairly well for me and I don't worry about it. The easier to clean tank sounds nice. If the new ones are quieter, that would be important. I look forward to getting a new one in a few months.
