All these cheap goto systems, that Mead or Celestron makes uses standard
DC
motors, vs. SS2K use stepping motors, lot more accurate.

The SS2K is a nice system; I used one on an Atlas for a while. Like the my
LXD75 and my CG5-GT, it gave the kind of accuracy you describe. Steppers
aren't one of the advantages of it, though. They are just another way of
achieving controllable motion. There's no reason why a stepper should be
more accurate than a servo of similar resolution. Remember that the Meade
and Celestron forkmounts are far more precise than any of the above, and
they use servos.
