ipodman,
Yep, that would make 'em NEMA 23s.
Also, per your link to the controller board your using:

NEMA is an acronym for National Electrical Manufacturers Association. They set standards for motors, connectors and other electrical items. One of their standards is for motor mounting flanges as you have already gathered.
Here's a
Minebea Astrosyn 23LM-K255-01 unipolar, 8-wire, stepper motor from Alltronics. From what I can gather the motor is NEMA size 23, 1.8 degrees/step (200 steps/rev), and rated at 1 amp. All that for $7.95 US each plus shipping/handling/tax.
Given the additional information you provided, I would steer clear of those stepper motors you were contemplating from Digi-Key. They all appear to be 2-hole, flange mount stepper motors with various steps/rev from 20-100. And they're a lot more expensive, to boot.
IHTH,
