Hey Mark,
I got a EQ6 and I'm pretty sure they always came with GOTO. GOTO is a function thats from the hand controller or computer (If you use EQMOD, which I've heard is the bee's knees), the mount itself just has to keep track of where it's pointing - which is already 'built-in' into the mount. Also the version on the handcontroller should be upgradable.
Can I just say that this is ridculously good price for a EQ6 + Pier! Hope you sell it soon Richard
