Because I always felt that my Sirius mount was a little light in the pants to deal with my 6" f/8 refractor, I bought a CGEM yesterday at Starizona in Tucson.
Last night I set it up and it worked great. Command structure much like my old Nexstar 11 GPS and accurate GOTOs with great tracking. A little noisy, I may put in some grease, but that is only happening during the slews, once it in on an object it is silent unless you put your ear to the motor cover.
I really like the big handles and smooth motion to get it on the Pole. I tried out the Polar Align and I don't see any need for a polar scope. It tracked Saturn for half an hour and it barely moved in the field of a 6.7mm eyepiece.
The system takes about 3 seconds to calm down with same eyepiece, much better than the Sirius. This is a much beefier mount than the big refractor has had in the past.
Lots of fun;
