Was your UPS an offline/standby model? I hope so. Online UPSs generate insanely noisy power that will eventually ruin whatever power supply is attached to it. Of course, the UPS switching from offline to online can also fry a poorly designed power supply. The best thing you can do is to just use a surge suppressor without a UPS and hope for the best.
Also, the comment "few dozen times" means you power cycled it a lot. It obviously can't be helped, it's just one of those things. Since 2000, I power cycled my Series 1 no more than a dozen times. There are some years I never powered it off or lost power, but I had to power it off to move it a few times and once to put a bigger hard drive in. Also once a year or so the modem would get stuck (remember they had modem problems) and a hard reboot was needed to get it working again.
Having said that, my brother has gone through 4 Tivos so far. In each one either the power supply or the motherboard went bad. Sometimes you just can't win.
