If it has to be a refractor (and I agree that a 6" or 8" dob would be better), what about this one:

(no eyepieces, but it seems a pretty good price, and you can pick up basic eyepieces pretty easily, or negotiate with the dealer)
I would also check with Andrews, and see if they can do a deal.
All the best,
