I can't speek to the quality of the motors, but you should be able to use a nema 23 size: http://kelinginc.net/SMotorstock.html
The STP-MTR-23079 at http://web5.automationdirect.com/adc/Home/Home is also a popular motor. The kelinginc motors being 8 wire are more flexable. i.e. can be run either unipolar or bipolar.
