The good news about buying a new unit, is new batteries. Any donated 
unit would have old or no batteries, you'd have to buy new ones for use. 
Typically gel-cell batteries are tens of dollars each plus tens of 
dollars shipping, bigger cost more. Your unit (reading the manual) 
probably uses three 12V 7Ah batteries; those are common enough, probably 
about $100 to replace. Probably replace every two-three years depending 
on how many times they get discharged (extended power failures). When 
they get cooked, they swell up, it's visible. Good luck!
