gecko and power sources

I have just recieved 2 servo motors off e-bay, and the prelim tests
suggest that 10 amps of current at 50-90 volts should be about right.
My problem is that I seem to be having difficulty finding a power
supply that can deliver. I would like to use g340 amps but cant seem
to find a transformer that can deliver that sort of performance
easily. There are 2 designs I am running around in my head ( the
system is a cnc sherline with emc/parallel interface ) System 1 is
a ~ 60 volt transformer, which can deliver 10 amps, running through
a rectifier with a big capacitor to yeild ~90 vdc, The second idea is
a 60 volt but cheap, 2 amp, transformer which charges a nimh/lead-
acid battery which supplys the current for short times of more than 2
amp draw.
So the question is : does anyone know of a cheap source for 10 amp
60volt secondary transformers, or does the battery/low current
transformer sound viable?


Thanks in advance for any help

P.S. I haven't bought the drives yet so if anyone has another
idea i'm all ears but the gecko drives sounded the most economical
