A lot of people have been through that particular 'hoop'. I went from a
very old homemade equatorial Gem, to the early CG-5, which despite it's
problems, after a lot of fiddling proved to be a suprisingly good mount
for the money, for smaller scopes, to a LX200 'classic', which was very
hard work to use for imaging, to a latter LX200, then to a G11, then a
NS11GPS as well, and on to an AP900, with a GP-DX for my smaller scope. Of
them all, the mounts that gave me the least success, were the LX200's. The
ones that were 'best value', were the GP-DX, and the G11. The one thing
that made really good tracking 'possible' with the LX200's, was an AO7.
The AP900, is the first mount I have had, that really carries a sensible
sized scope, and tracks _well_.
It is the area where to my mind the 'mass production' scopes are really
weakest...
Best Wishes
