Hi Jerry,
Im going to spend the extra and go for servos.
What are you thoughts as far as adequacy of these servo's?

Could I get away with running them from a single 60V power supply? I doubt I will ever find a use for their peak RPM. How many amp supply would you say is required? I read somewhere to purchase a supply which equals 60% the combined continous amperes of all drives, is this correct?
My primary concern is I would like to be able to add a 4th axis eventually and not have to replace the power supply.
Ive been searching around for servo's with no avail, most online retailers seem to be selling pretty much the same products.
