If you are looking for technical information you dont look on EBAY.
There are a ton of advertisements on here to look at, most of them will give you the information you seek.
There are only 2 things to be concerned about and that is how powerfull do you need the stepper motors to be. How much current (Amps) the steppers require, all of the boards for the voltages and current are adjustable so that is no problem.
As far as I am concerned the small steppers that come out of scanners and printers are almost useless for running a decent machine.
