Honestly the best bang for your buck would be an XT8 Orion Dobsonian. It falls right at your price range and is an amazing scope for the money. It would take you years to outgrow it. I had one for awhile and the moon was mind blowing. Saturn and Jupiter were very clear as well as some of the more fainter galaxies. Plus it is an excellent beginners scope that can easily, with the right upgrades, become a very heavy contender with much more expensive scopes.
