We've had several APC Smart UPS'es fail catastrophically and without 
warning.  In one case, a 2200VA unit literally caught on fire!

A bit over a year ago, we bought a CyberPower PR2200LCDRT2U (2170 VA 
1600 Watts) rack-mount UPS, which was about half the price of the 
equivalent unit from APC.  So far, it's been fine, but time will tell if 
it's better than those we've previously bought from APC.
