Powering Stepper Motors

I’m looking at getting these stepper motors: http://www.ebay.co.uk/itm/Two-Arduino-5V-4-Phase-Stepper-Motors-with-2-ULN2003-Control-Boards-Pair-/181086781943?pt=UK_Sound_Vision_Other&hash=item2a299d01f7

Is it possible to power the both of them using one Arduino Uno?

Thanks

Power them from the Arduino regulator? I do not think this would be advisable as you may over-load the regulator on the Arduino and cause other problems.

You could certainly control both of them using an Uno, but I would he tempted to supply their power separately.
