I agree with Mick - if the scope is for visual observing, nothing beats aperture. A 10" is a damn good instrument though. It also fits onto an EQ6 mount for astrophotography without straining the mount too much. It comes down to how big a scope you can carry and set up. The best telescope is one you will use most frequently. A visit to an astronomical club for a look through various scopes and eyepieces might be a good idea before committing $$$'s. Do you have to transport it to another site by car? If you can handle it then the GSO 16" is great value:

and it's in your price range.
For eyepieces, the Televue Naglers are hard to beat for quality and range, but equally good are the Pentax and Vixen LVW ranges also. If you get a couple to start with, you can always add more later. These can be a lifetime purchase.
