thanks again for the suggestions, wasn't sure if it was possible or not.
To answer a few of the questions, I have 3 game machines that I'd like to not have any power surges hit, 2 athlon 64 setups and 1 athlon xp setup. All are CRT monitors, 21 inch, 19inch, and 17 inch. I'm looking for as least expensive as I can. Like I said I have 3 game machines(played daoc for too long and ran several accounts at times), email machine, server, and general use pc. Nothing real vital on most of the machines but I'd like to avoid any power surge issues, blew a router awhile back because of a squirel on a power line caused a few brownouts.
So bottom line looking for advice on how much I can load a ups with just for a few minutes if I have brownouts or give the pcs enough time to shutdown during a poweroutage.
