One cheap and simple way to get PUSH TO is to use the new Celestron Starsense explorer system. You purchase one of their cheap refractor scopes, remove the starsense bracket from the scope, remount it on your scope and give the little refractor away to a novice astronomer to learn the sky. You could make several brackets for different scopes and move the system around as needed.
This platesolving star location system works very well using your cell phone combined with the free Starsense APP. The scope does not need to be leveled and you can even move it around the yard without having to worry about the system loosing its PUSH TO calibration.
You can read a lot more on how some of us have been adapting the system to our larger scopes here. Unfortunately Celestron does not sell the system by itself for now and you can't unlock the APP unless you have the code located inside the telescope box.
