CMC or Panther. I've had a few guys coming into the shop lately looking for CMC replacement actuators. From what I'm understanding, CMC doesn't sell JUST the actuator, they'll sell the entire unit though, for about $550. Talked to a guy last duck season who uses a Panther, and he loves it. I have not used one; I have used a CMC in the past and it works as designed. If you get the CMC, ditch the relays and replace them with a winch contactor.
