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.

Fork mounts has large worm gears, maybe 3x larger than the GP mount has, may
be that's why. I owned a fork mount LX-200, was OK, you stuck with the same
tube though, so I prefer EQ mounts for many reasons.
I didn't own these newer EQ mounts from C or M you talking about, so I
can't compare them to the SS2K, which has been out 4-5 years or so. I'm
happy with the quality and accuracy of the SS2K .
