It would be good to mount an encoder on the mechanism to tell if it was slipping and give you closed-loop feedback as to the position of the turret.

As to the OP's question, I've used a couple different mechanisms, including a 60 tooth #35 pitch aluminum split sprocket (used in go-karts) and the Gates Powergrip GT-2 timing belts and pulleys (like those supplied in the kit).
