This is pretty late in the discussion, but here's my advice: start with a smaller decent quality dob (6") -- we started with an Orion SkyQuest XT6 -- and get 2-3 decent eyepieces (10mm, 25mm, 32mm) and a 2x Barlow. You should be able to get all that for $750. That size scope is easy to carry and setup. With reasonable eyepieces you can do lunar, planetary (Jupiter/Saturn), double stars, star clusters, and nebula. None of it will look like the astrophotography, but seeing it yourself can be so satisfying. If you find you like it, there is no end to how much you improve your tech and how much can spend in the process! Also, check out CN (www.cloudynights.com) for tons of advice.
