Greg:
Please don't do a write-up on the CGEM. I am afraid I'll read it and then buy one, just because...
I have an Altas EQ-G currently that's been great, but I think Synscan is light years behind Nexstar in features. As an avid double and carbon star observer, Synscan's lack of a slew-to RA and DEC feature is unfortunate. Adding targets to the User Defined Object catalog is cumbersome, and you must keep a separate log mapping UDO slot to object, which multiplies the "stuff" you have to take outside. The CGEM is tempting for the software alone.
Regards,
Jim

Just found this thread and waiting for the writeup... 
Perhaps whoever reviews it could consider these novice questions:
1) PPEC - do the servos make that possible, or is the assumption that nothing messes with the mechanicals between "parks"...
2) PPEC is great, but with my EQ6, the PEC curve is different every time I measure it!  Will this mount let me download the PEC data for multiple turns of the (worm) screw, mess around with it, and upload it back?
By the way, the polar scope is listed at $62 on Celestron's website. I'd be truly aghast if such a device (at $250) cost almost as much as my Canon 10x30 image stabilization binocs!

Hi Greg
How much of this CGEM mount is plastic? I'm considering getting one, but would have to import it - no chance of finding one here so I can check it out first!
Cheers

Another great thing about the CGEM software is that you don't need a polar alignement for the GOTO to be dead on. A 3-star alignment with the mount pointed in the general direction of polaris is good enough for spot on GOTOs. Not possible with the Synscan, if you don't line up polaris just right even a 3-star alignment isn't going to work well.
If you bump into a mount using Synscan then forget it you have go through the entire setup process again, but with the CGEM you just replace your alignment stars with any stars you want and your back in business in under a minute.
I really liked my Synscan until I got the CGEM, now I hate it. I wish I could use a Celestron HC on my Sirius mount.

Rick, as You probably read by now, some CNers replaced the "plastic" knobs with ADMaccessoires knobs;

Interesting. Although in all honesty, I don't mind the plastic knobs for the most part so far. The important parts of these knobs are still metal.
Still much better than the CGE for adjusting the darn thing.
