If you have a C9.25 and want to do visual then you will be disappointed with suburban views unless you get to around the 130mm aperture. Smaller than that and you really only get widefield views. Use a high powered eyepiece on a 100mm scope and you get really dim views of anything other than the brightest objects. As far as an impressive view of the Planets that would be your C9.25. A 130+ aperture is needed for that in my opinion.
So for visual perhaps the 127mm North Group scope would fit your needs.
A 2nd hand Tak FS125 comes up every now and then. A doublet is not ideal for photography as there is too much chromatic aberration but you can process around that to some degree.
I agree with looking at Stellarvue and also check out APM. He has some nice large aperture cheap doublet visual scopes. Perhaps that is the go.
They were way under $5K.
