ditto AN, I guess it just depends what you're comparing it to. All of the GSO optics in the 10" and 12" models are f/5, which would make comparing against your f/7 quite difficult.
Quite funny hearing about the sales spiel.. 2 bands on jupiter, i bet
I guess when you look at some of the imaging done with these optics, both planetary and deep sky stuff, and compare against a much more expensive Meade or Celestron SCT, they're producing good quality stuff.
Though again, I don't know that anyone has ever done a side by side of a GS scope versus a custom made scope with a premium mirror.
