Excellent quality motor. Keep in mind that this Nema 23 motor draws 2.8A per phase (two phase motor) so it should not be driven by small motor drivers. Follow the advice given in the "questions" section and pickup a motor driver that handles this beast. I picked up a few decent ones from ebay and love this thing. It has plenty of torque and speed for my application. I am looking into getting a tiny motor controller or a gshield.
