Yeah, I've tried one with the thumb control, friend of man has it on his. My hands are just a bit too crippled up to be able to use it anymore, guess I'll have to stick with the foot pedal.... Lack of mobility, decreased range of motion are the two main reasons I'm going to build the new rotisserie with a hydraulic motor to rotate it remotely, easier for me to turn the car into position rather then try to turn my body into position!!!!!
