APC makes GREAT UPS's and have good support. I once blew out an APC by
miswiring a switch on a computer (don't ask). I called tech support,
they agreed that what I told them had happened shouldn't have happened,
and shipped me a new UPS for free, without any hassle. From that point
on, I swore I'd go APC first.

Not that I know of...there's daemons you can install for that purpose,
though.

Generally you need to add up your power requirements and match the load
to the UPS's power rating.
