Matt,
FWIW your experiances are exactly what I found with this mount.
The DEC axis simply could not be used during guiding it might work for a while but was unstable backlash being 10s plus. I had the worms adjusted and it worked for a while but soon slacked off back to its bad old ways. I had to offset alignment and set to DEC to correct against the drift to be able to work at all. Even then I was limited in exposure times. I had a VC200L on the mount though and was using a Canon20D and that was too much scope I guess (0.7"/pixel).
I lost patience and sold it.
For visual use it is ok, a good and portable mount. With a small, short fl scope it might just be acceptable for AP. With the new motor control board perhaps finally the mount is meeting its potential.
I have a G11 now with which I am extremely happy. It just works but those smooth flat correction graphs stll make me smile every time....
