They sell stuff for computer equipment protection, and their mark-up isn't anywhere near what monster and that stuff sells for. I bought a $40 surge suppressor/line conditioner. It was the professional line, which covers $25,000 for any damage, and a lifetime replacement on the actual surge protector should it be damaged. They make high quality stuff. All the servers in our office (10 of them) are running on their battery back up systems.

This should take care of your problems, but if you are having problems with brownouts, you may want to consider a battery backup which will kick on the power when it dips below 105 volts.

Hope this helps
