My experience with Belkin is stay away from them.
The company I work for used to use Belkin UPS' and the guy who bought them basically says he bought them so that surges will kill the UPS instead of the computer.
I've witnessed at least three of them go bad after power outages in just the past 35 days or so since I started my job.
We have a bunch of them in the building, probably about ~70, but I think it seems they blow a little too often.
I will say that the ones we're using are cheap CHEAP ones, so this might not be a bad deal, but my experience is Belkin makes crappy UPS'.
Hope this helps, Ryan.
