Have a Dob Driver II? Want your scope to track and have go-to ability? I have the Roboscope 4.1 software, cable and complete instructions to drive your scope. This sells for $99.00 plus shipping from the Tech 2000 folks. There was not much interest at my first asking price of $60.00 so I'll kock off 10 bucks and sell it for $50.00. Includes shipping by priority mail.
