Eaton Powerware used to be Best, they made the very good FerrUps series.

Re: batteries, most all UPS's I've seen use various standard VRLA 
batteries (Valve Regulated Lead Acid, often mistakenly called Sealed 
Lead Acid, or Gel Cells), readily obtainable from vendors like 
www.digikey.com, assembled into packs...   with a few exceptions, you 
can use the generic equivalent battery, much much cheaper.   I  
resurrected a dead SmartUPS 2000 that was going to be tossed at work by 
replacing the batteries with 4 x 12V20AH Panasonic VRLA, which happens 
to be the same size my motorcycle uses.

Now, battery prices have gone up considerably these last 2-3 years, lead 
prices are very high, as are transportation costs.
