Anecdotally, I stay away from APC after a couple of bad experiences - one of the BR1500Gs I had protecting my server failed spectacularly, one of the power transistors exploded (literally) filling the room with smoke as it continued to try and operate. Luckily, someone was home to yank the plug.
The replacement (brand new) BR1500G failed in less than a year.
I do still have a few NS1080's protecting desktops and AVR, tho. No issues with those so far, except surges have taken out the AVR, twice. Haven't been able to specifically blame the UPS for not stopping the surge(s), tho, as it could have come in from a different path. I put a LE1200 behind the UPS and the AVR still got popped a second time.
YMMV
