to IIS, styleman333! The SW 8" Dob is a nice choice and that's not a bad price either. MyAstroshop have them on special for a bit less at the moment and are offering free freight too, but if you found a dealer near where you are go with the locals I'd say, for the ongoing support.
In off-the-shelf Dobs there are basically two choices, the GSO Dobs from Taiwan, and the Synta Dobs from China. The Skywatcher is a Synta dob. IMO the Syntas have a bit better ergonomics thanks to the tension handles. They also have a bit better finish (esp the paint on the steel tube). With GSOs you tend to get more upgrade options (Crayford focusers, mirror fan, finderscope). Optics are probably similar. I don't think you can go wrong with either scope. You are getting a hell of a lot of scope for $400-500.
