Hi there and
to IIS!
I started with a 10" dob, the same as you. I ordered a round table platform from Brian Reed in about June 2005 and owned it for 18 months. It was brilliant. I used it for visual observing as well as high-resolution planetary imaging with a 5x powermate and a ToUcam and then a DMK.
I sold it to rmpcb who now owns it, and loves it just as much
You really can't go wrong with them. A great piece of gear.. gives you tracking, and still with the convenience of observing with a dob - something a newt on an EQ mount can't deliver.
With an argo navis or other DSC's, you get push-to as well as tracking. I loved my setup.
