Commercial solutions ServoCat or SiderealTechnology are the two that jump up to mind. Both can be used for slewing and tracking, for goto you need a Computer or DSC to control them. The two DSC's that work with both is our very own Aussie made ArgoNavis, and the US Sky Commander.
Then there is the one that started it all Mel Bartel's stepper system, you can either buy it or build it yourself with some surplus parts. This system requries a computer running Dos to run Mel's controll software for goto and tracking.
For any of the above some amount of DIY is requried and you can also add surplus parts to the mix to save some money on the motors and gear boxes. Have a Look at Gototelescopes.com Lenord his site has lots of conversions he has done and helped do.
ServoCat + AN is the most popular system for the Big Dobs. You could start just with the AN as a DSC system and later invest in the ServoCat.
The Siderealtech system can work out cheaper if you get surplus motors and bits.
The AN is arguably the best accessory you could get for your DOB.
