Peaches, how often do you have blackouts? I'm in a suburban area so I'm probably a bit more lucky, I can only remember a 20 min blackout in the 4 years I've been living here. Plenty of sub-second "blips", but the UPS catches those.
I've also been looking at mini (10') shipping crates, if I've got the gen in the back yard I may as well put the computer room there too!
