I have an APC Back-UPS XS 1000, it's like a consumer version of the RS1000, I think the main diff is iirc the RS1000 can take an extra external battery and the XS can't, but the XS only cost me something like CAN$100 on sale. Works great, my laptop, hub, cable modem, monitor and PC are all on it, only draws ~250W total (two hds, p4 2.4 at 100%, x800 in 2d... hard to check the APC util in 3d
). Also remember battery time isn't linear with your load as a proportion of maximum... I didn't realize this UPS would be such overkill, but 250W of stuff on this UPS will run for around 21 mins compared to, say, 6 mins fully loaded, which is great.
