I recommend that you use Clearpath servos. It is a step up in budget, but the motion is much smoother and there is no vibrations which are somewhat inherent in steppers. Linear motors are great, but are overkill unless you are concerned with the lost motion inherent in any screw, r&p, or belt. servos and double nut ball screws are adequate for almost everyone (including Mazak, DMG, HAAS, etc).
