Iddon one thing you didn't mention was what your going to use this new telescope for. If your getting into astrophotography maybe one of the other of these two may be of use.
If your wanting to do visual observing a dob mount is by far the better option.
Don't be fooled into thinking that your going to get one of the only setups in the world that is great for both visual and photos. There isn't such a beast (certainly not in the sub $3000 range). The disiplines are almost muturally exclusive. Great tracking, super fine focus, multiple telescopes (guide and imaging) on the same mount, smallish apatures (for photos) vs large apature preferrably alt az for easy star hopping for visual.
