Well i didnt get away with the tax so thats another £43 to add to the £189 for the Gecko , so if id checked around and wanted the hassel of conecting drivers and break out board up , the price wouldnt have been much differant than buying the gear from Zap in the first place. As Gary says i dont think the performace will suffer as im going to use 48v 7.3 amp power supply , its just that youv,e paid for the motor holding torque and would like to use the full spec of the motors. Its for a mini mill so i think it will make enough speed for what i want ..... time will tell .
