Its always good to see new and interesting telescopes come on to the market. I have not had a chance to see the review Glen mentioned.

Given that the classical cassegrain is considered good for high magnification visual observing, what advantage would the GSO 10" f12 cassegrain have over the GSO 10" f4 Newtonian? Especially as it is not at the optimum f15-f20 focal ratio.

Andrews has the truss 10" f4 newtonian at under 2k$. Even if you added a TV Paracorr you would be under 3k. I guess the proof will be in the pudding so to speak.
