Valin,

I have the Safety Trim in my ES. You can calibrate the airspeed switch to whatever airspeed you want and adjust the trim speed for the high and low airspeeds. It works great. I run the trim at full speed in the white arc, and about half speed above that. I don't have to tap the trim hat switch in cruise and I have the fast trim when I'm in the pattern. I don't know of any product that is continuously variable. The Safety Trim also has a couple other features that are nice to have.
