Losmandy G-11 DSC

OK, I'm asking Santa for some of the hardware to add DSCs to my Losmandy G-11.

I've heard that high-tick encoders can be ordered for the Losmandy DSC hardware...has anyone here done that?

Did the improve pointing?
What does it cost to upgrade?
Will they work properly with the current SkyCommander?

Thanks,
Forrest
