Sticking my or in. My village is the same, so I have a UPS on the TV/Digibox as well as a couple in the office (with the router and hubs plugged in too). I have two desktop PC system units, a kvm switch, one CRT monitor, a print server and a an ADSL router split between two 650AV UPS boxes and have stayed powered up for fifteen minutes (a deliberate test to see how long I really had).
I've tried a couple of other brands now, (Belkin and Trust), but am firmly in the APC camp. The Trust UPS (a Power Master PW-4075T) died after only a couple of years click here.
For around the £90 mark you can get a APC 650VA (details click here). I got the last one from Amazon. They come with a free copy of PowerChute and can be set up to automatically shut down your PC in a powercut. You just plug them into the network and install PowerChute onto your PC.
