Hi Sergey, IM Service do some nice servos that are ideally suited to a Sherline <http://www.cadcamcadcam.com/index.asp?PageAction=VIEWCATS&Category=11>
They also do some nice servo drivers though they are step/direction so you can't use the encoders as a DRO. Steppers do work and can be reliable but they are slow. Basically you need to decide if the extra speed is worth the extra cost. I personally don't like steppers so I would go the servo route.
