Mor importantly get a Trip-Lite IsoBar like
THESE as a UPS (unless its an exspecive one around $2000) dont run the power through the bettries unles there is a power outage (they switch over to bettery when the power goes out) they offer very little surge protection whereas the Isobar has the proper protection and they garentee it including the equipment plugged into it.
EDIT: The cheeper UPS systems still connect your computer directly to the AC voltage comming in so your not as protected as they like you to think.
The exspencive ones actualy seperate the incoming power from the outgoing power so the power is actualy comming from the battries all the time.
