Well now, I can't understand why everyone dislikes APC so much? At work I have a Silcon that we are replacing with an infrastucture (much more scalable) . Granted, the Silcon is the size of a small shed, and the new infrastucture is 4 full size racks with an 80amp 440 wired directly into it (the building is 3 phase). Now sure this is way more than you need but APC makes very nice conditioning and battery backup in one units for just a single workstation. They range from 60-100$. I highly recommend them, and I wonder why folks are badmouthing them.
the Back-UPS ES 500 for example is 60$ and it *is* also a power conditioner....
