Request for Recommendation for Power Supply

Yes, another newbie question. I am adding CNC capabilities to my
Sherline Model 2000 mill. Mill hardware is Sherline motors and
mounts. Steper control circuit is Dan Mauch's 3-axis, 2A driver
board. Software has not been selected.

I have completed assembly of the driver board, and now I need
recommendations for an appropriate power supply. I am looking for
something capable of powering both the mill and a future conversion
of my Sherline lathe. To assist those who may respond, the Sherline
motors are 3.2V, 2Amp. Also, I plan to mount a stepper to my rotary
table and add Dan's 4-axis module.

A secondary question concerning the lathe conversion is, is it
practical to use the same driver for both the mill and the lathe, or
should both machines have their own driver circuits and share the
same power supply? The two machines would not be operated at the same
time, but I prefer simplicity over trying to save the cost of the
driver circuit.

Finally, recommendations on software would be appreciated. I already
own TurboCad Ver. 6 and based on recommendations from users on the
Sherline list I am leaning heavily towards purchasing CNCPro.

TIA

Dan
