[rescue] Source for used UPS?

[Scott Newell]

I'd like to get a decent UPS.  Probably 1.5kVA or larger, 120V, single
phase.  I'm ok with buying one with no batteries and getting batteries
elsewhere, if I can save some bucks that way.  Is eBay my best option, or
are there companies that specialize in affordable used battery backups?  

I'm located in the southern US, and we have a loading dock and forklift...

thanks!
