I expect that most standby power supplies can switch fast enough to
keep your equipment alive. We are using one from Topaz which switches
in about 10 mS. As long as it is less than one cycle of 60 Hz power
you will probably be in good shape. I tested the Topaz on a florescent
lamp: it stayed alive.
If you do go with the much cheaper standby instead of a true UPS, make
sure you have a regular testing program for the standby. (e.g. unplug
it from the wall every month or so) Otherwise you could be driving
around with a flat spare.
