anyone have an opinion or experience with Alpha Spid rotator? I am tired of the problems with my tailtwisters... currently the one turning my tribander at 150 ft is stuck north east. The spid seems to be priced less than new tailtwister, only uses 4 wires, runs on 12 volts and will fit in a rohn 25... only requires an adapter plate.... what is not to like? thanks! 73's Cort K4WI
