We were all set to buy a dozen APC 750s, a half dozen or so APC 1400s, and
another hald dozen APC 2200s a year or so ago.  We had approval for the
purchase from the director and provided the exact model numbers and
quantities to our purchasing officer.  Our purchasing officer came back
sometime later and suggested we purchase Minuteman UPSs because they were
on sale at the time.  We never did get to purchase any UPSs.  grr...

That said, Minuteman's Entreprise UPS series looks to be pretty good.  
Does anyone have any experience with them?  We were planning on buying 
large 2x00VA UPSs to handle Enterasys 6000 chassis (pl).
