And geting rid of the added expense, a power supply capable of driving 3 motors the size those drives can handle would run you down at least 300 bucks... if you can find one, if you dont, you have to build it yourself... and we have all seen all the questions regarding power supply calculatons.

PS. I dont know it I am allowed to post prices here, but lets say that they are cheaper than a G202. FOB China, thats the down side.
