Hi,
if buying 23 size steppers look for as low inductance as possible, 1mH preferred and reject anything over 2mH.
In order to make low inductance steppers manufacturers use fewer turns of a thicker wire, which in turn requires more current to get the same
torque. Thus the steppers you are looking for will tend to be high current devices, say 5A or more. The 570oz.in motor linked to by the previous poster
has an inductance of 2.5mH, so on the high side but still quite respectable.
I'm not a fan of switch mode supplies, they are too tender. Linear supplies like these:

Are very much more robust.
One of the most common reasons for failure of witch mode supplies and/or stepper drives is BackEMF at deceleration. All motors generate
energy back into its nominal supply when the motor is decelerating. The ability of the driver and/or supply to tolerate these overvoltage events
is the principal difference between good and bad driver/supplies.
Gecko is the industry standard for robust drivers but are not cheap. There are plenty of good Chinese made 80V drivers at very fair prices...get some.
Remember you'll have these drivers and power supply for ten years or more if you buy well in the first place, but throw them out in months or less if you buy poorly.
