It seems to me the CDK and RCOS alterntatives would be far more expensive and would be under utilized if only used for Visual astronomy.
I am guessing if the Motors in the LX200 are still funcational and are Servo motors then it would be very easy to fit the Sitech to this. I will even donate my Sitech for testing if that woud help. I would hate to see it put out to pasture, it has so much history to it. So many people have used it.
