Those are sneaky people...they hide the voltage it's not on the stepper spec page....not even a chart...so, I suspect that they are overdriving the steppers(higher voltage...if you go with geckos set the current limit to around 3 amps any other driver you'll probably be safe to add a current limiting resistor of a little over 10 ohm, 100 watt to each stepper supply wire....it looks like they are 32 VDC...so a supply between 30 and 36 vdc at 18 to 20 amps should suffice.
