Hi, i would like to purchase a good nema 17 motor, but I want one with 40mm length like ultimaker motors. Does anyone recommend a seller for me?

This seller and motors are a good choice http://www.aliexpress.com/store/product/Best-sellers-5pcs-NEMA17-CNC-stepper-motor-58-Oz-in-40mm-stepping-motor-1-3A/704350_1129248380.html

@Eclsnowman Do you know the length of the shaft?
