  You mean this thread?

  That was mainly about surge protectors.  It never got into UPSes,
other than to say "UPSes are good to have, too".

  You definitely take an efficiency hit.  However, in this case
(extremely dirty power and extremely expensive and sensitive
equipment), I believe we don't have much choice.  We need something
that can handle frequent severe sags as well as all sorts of
distortions.  A stand-by UPS will be tripping on and off battery all
day long, and be dead within a month or two.  That's inefficient, too.
