Does anyone know how the 3b1 power supply holds up when fed the square
wave output typical of most UPS's?  I know this causes a problem for
some switching power supplies.

Any favorite brands?  I see James Electronics is selling a 200w
"trip-lite" brand UPS for about $240, and for a while, ERAC was
selling 400 watt Elgars, with "cosmetic defects" for only $180.
