Since about '07 I was using 1500VA APC Smart-UPSes. These are the ones that buzzed along with the ZT60 when it decided to buzz (usually with heavy white or bright content). (I stopped hooking up the plasma to the UPS once I realized that that was what was happening. (And the subwoofer too at some point; it had two repairs done to its board early on.))
I also had a slightly newer one of them for my old Mac Pro tower that I got in '08, thing about it is that the fan was always on, unlike the slightly older two. After the tower was replaced with a quiet computer earlier this year, and after the UPS battery died yet again (and the indicator lights on the UPS became unpredictable), I decided it was time to move on and went with a CyberPower Smart App Sinewave UPS (model PR1500LCDN)... It normally runs silent (fan off unless it's doing its thing), and is a lot quieter when the power is removed.
I liked it well enough (I can actually log into it to see what's going on with it and change settings from my Mac) that the other two APCs for the home theater got replaced shortly thereafter. Time will tell how well they hold up (got one bad one along the way) in the real world, since thunderstorm season is over, and things tend to be a lot tamer in the off season, but they seem to be working fine.
No update on buzzing, I just haven't heard any lately, nor have I tried anything else yet to instigate it otherwise.
And I think my back has finally recovered from moving them (both the old and the new) about a dozen times or so, though my elbow hasn't been quite the same since. (Old/bad ones are in the basement now, just in case. The bad ones will be recycled one of these days; the good ones plugged in every once in a while, might come in handy some day.)
