CNC power supply

Hello,
I am currently making a CNC for my lathe and mill.
I need to get a transformer for a power supply, hopefully something that will not require an arm or leg.
I need to generate up to 65 V at 0.75 A. This will power four stepper motors.
I there a way to do this?
Is there a suplus outlet I can get these on the cheap?
Any schematic?

Thanks
Arnold
