Seriously though, the reason I still have the GM8 is that I couldn't part with it. As others have said, it is a great mount. Yes the tripod could be a bit more solid, and no it won't handle 30 Kg, but you will be surprised at what it will carry.
Before I bought the G11 I had an 8" meade SCT plus 80ED, finderscope for each, plus 300D, and Losmandy guide rings. Add to that the side by side plate I made up with 2 losmandy saddles and a dovetail bar. Total weight was pretty damn close to the limit if not over it. Did it worry the GM8. Not in the slightest. Here is an
