Is there any cheaper oximetry solution for ResMed machines?

I’ve got the CMS 50F. It works great with Sleepyhead. Getting the time to be in sync with the CPAP data can be a bit of a chore, but otherwise it works great. I’ve only used it once, but I did confirm with it that during my CA events, my oxygen was dropping down into the 88-87 range. I’ve since made some changes and eliminated most of my CAs, so for me at least it was a useful data point (and I’m now feeling much better).
