I purchased this ASCOM autofocus control system with temperature compensation and dew heater controller 2 1/2 years ago based on numerous positive reviews on IIS, Cloudy Nights, and Stargazers Lounge. It has worked flawlessly on my Esprit 120, but I have just cross-graded to an Optec FocusLynx based system ($$$) to allow me to easily focus control multiple OTAs.
Current adaptor suits Esprit, Evostar, ED80, and similar focusers with 25mm focuser barrel diameter. Can alternately attach for other focusers by making a mounting plate attached to the focuser underside. I am more than happy to assist with mounting setup, if necessary.
