I want to install digital setting circles/optical encoders on an older Parallax GEM which I'm fitting with new Byers gears/worms @ 11 15/16". I need some feedback on the various packaged systems out there..or single item suppliers unpackaged (homebrew). I don't need goto..just better accuracy then mechanical setting circles.
