I bought a rebuilt from MotoSat and installed it today and all is perfect.

I'm sure it is a new unit, but when you purchase older style equipment, they list it as rebuilt as not to hurt the ones who purchased the same unit as new a year or so ago.

I do not know of anyone purchasing one of these antiquated systems in a long time but I had to go the most economical way.

Thanks for the heads up, but it's too late and I should have thought of Richard.
