I've had good luck with Refurbished UPS
<http://www.refurbups.com>. They rebuild
APC units, have decent prices with full
warranty.
Short of a full outage, a line conditioner
works equall well (APC makes several good
dones, 1250VA being more than enough for
most PC's).
After that you can get a "Smart UPS", which
is basically a line conditioner and a battery
in one box. This solves your flicker problems.
A Smart-UPS 750 will probably handle anything
you need for a desktop and L[CE]D screen, for
two of them you can get a 1.5KVA that will give
you plenty of time for shutdown even with two
machines.
For a home unit, your best bet is to size the
thing for a reasonable shutdown period rather
than try to keep everything running through
a potential blackout. Reboots don't take that
long and the cost+overhead of running an oversize
unit adds up. You have a different calculation
for servers or racks, where uptime is more of
an issue. The bigger ones also weigh a helluva
lot more, which doesn't sound like anything
until you break a desk or warp some shelves
unnecessarly :-)
