I use an UPS at work which comes from a place called KNAPCO which advertises
regularly in Computer Shopper.  It's a High pass filtered square wave output
standby style UPS that switches in 2ms.  It has been reliable.  A very
nearby lightning strike did zorch one, however.  It also took out a phone
and a MAC serial port.  They sent us a replacement board for free but I
had to do some soldering to put it in.  We use the 550 watt model at work
which they advertise for $399.  Back when we got them about 6-8 months ago
we got a quantity discount and got them for about $350 each (we bought 3).
They have a 200 ($279), 350 ($299), 550 ($399), 800 ($599), and 1000 ($699)
watt models.  These are some of the better per watt costs I've found.
