The 1224 was designed to drive the channel master dishes. 10 years ago they wasnt around anymore as they stopped making them around 15 years ago. The superjack actuator was the next best thing that would drive a larger dish. The superjack actuator would not go as far [east or west] as the 1224 does giving it a better advantage. I was lucky to find mine brand new in its box a few weeks ago. It cost me a small fortune but its well worth it. I totally trust this motor as now my dish has finally found its lifetime partner...the 1224 :)
SSS who sold them, probably were you got the superjack will also tell you that the 1224 was the only motor they would trust on a cm 1.2. I know this because Dave from SSS told me a couple of weeks ago.
