Servo motor selection

First, an introduction...

I'm Jake, and I'm new to the group. I'm currently waiting for my new
Grizzly G3012 mill to arrive. Its backordered, so I've got a few
weeks till it arrives.

I'd like to do a motion control setup for it. I'm pretty handy with
electronics, and I understand most of how this works. However, as
for chosing motors I'm at a loss.

I'd like to thank Mariss for the wonderful top 10 list. Its helped
me greatly. To quote:

"7. Bewildering choice of motors, encoders, servodrives"

I'm offcially bewildered. I'm deathly afraid of taking all this time
(and money) and having underpowered motors.

The camtronics people sell peak-600oz/in motors 50oz/in per amp for a
price I can afford. My question is: is this a good way to go? Will
these be strong enough to handle a mill this size? Should I go with
a direct drive, or timing belts? Is there a good conversion factor
from stepper to servo oz-in ratings?

Any help is appreciated, and I do appologize for the post. I haven't
seen a "guide to chosing motors", other than a really confusing bit
about coiled ropes and such that I found in this forum. Maybe I'll
put something together with all my notes once I've gained some
experience.

Thanks for your time.
