[Skunkworks] UPS with AVR pass-through

Anybody know where to get a UPS that has AVR pass through (i.e. some sockets are on the battery and some are not but still get the voltage protection). I'd like to get my router on the battery but not items like a printer or scanner - although I'd still like them to have protection. None of the UPSes I've seen in stores locally have this but maybe there's a store people know about with one?
