Go the Dob for sure as a starter scope. As many have already stated that you will still need to know stars to get a GOTO Scope setup anyway. You will see more in a Dob and knowing what stars and objects are above you is really easy now.. Most of the Oldies on the site use charts or computers LOL but young operators use Mobile Phones and Iphones. Thier are some fantastic apps and some free ones that allow you to point your Iphone at objects in the sky, and tell you what they are. In fact you can ask them to guide you to objects you want to see, then point your telescope at them. I use star walk on the iphone 4 and you can also get stellarium for the iphone. Spend all your avaliable money on the biggest DOB you can handle instead of paying for electronics..
Good luck with your choice and welcome to the site..
