Well, the TV and Blu-Ray player don’t have discrete power functions.
Had a bit of luck, I found a Harmony 900 for $150.
It's a refurbished one, but so is the 880 it's replacing.
And that's being ordered as it works out, my mom likes it, and can get extended coverage.
Thanks for the input! Honestly, if this one goes belly up, I'll probably really push for either a JP1 or URC. If I can at least backup settings from the URC as a precaution, that will be good enough. Just wish the stranded remotes had all options on them.
