Make your own ups. I seen a tutorial for this before. Take a car battery charger connect it to a decent sized car battery. Take A 12V -> 110V power inverter an connect it to the car battery also. Now the car charger charges the battery and the inverter draws from that battery. Power fails the charger quits charging. But, the inverter keeps running off of the battery. In the article that I found, can't find it anymore, the guy had his computer, 17" monitor, printer, scanner, and portable phone base unit all running off of the car battery. It ran for TEN freakin HOURS!!!! Sure it's a bit big and clumbsy. But, it's a heck of a runtime. The only thing that I don't remember is the size of the inverter. I would probally at least go with a 800W. Someday I plan on doing this. EDIT: modem is powered by the computer. Phones are powered by the bell wire. Router can be hooked into the ups. DSL\Cable modem can be hooked into the ups also.
