I think this is pretty much the design standard, at least for small
self-contained UPSes.
There are some amazing deals out there from time to time -- I got a new 300
VA APC UPS for $10 from Staples after a mail-in rebate. It's not enough to
power everything computer related in the shack, but it supports my CPU
quite nicely. Since installing it, I've never had an outage of more than
about 2 seconds, but I've had hundreds of the little glitches and dips that
would have caused my computer to reset otherwise. It's very pleasing to
hear the UPS beeeeep and know that I've just dodged another bullet,
especially in the middle of a good run.
