True to form, this list provided me with almost two dozen answers
before I even got to work this morning. Everytime I think the signal
to noise ratio on the net is getting too abysmal, I just need to send
a question off to you guys...

Anyway, far and away the most common recommendation was APC
(http://www.apcc.com/), which by all reports makes very reliable UPSs.
They also have software called PowerChute to manage regulated
shutdowns. Other recommendations were given for Best Power and Exide.

Raymond Rodebaugh <ray@therad.rpslmc.edu> added some additional
considerations:

Jim Harmon <jim@telecnnct.com> very helpfully provided some guidelines
for sizing a UPS, too.

Anyway, it looks like I will be looking into an APC Smart-UPS 1400,
which seems to run just shy of $700, and the software which goes for a
little over $100.

Thanks to everybody for the help.
