Whether or not to upgrade to the CP4 is a personal choice. It really depends on how you plan on using the new mount. You should study carefully the features of the CP4 controller (and the upcoming keypad upgrade software) and see if the new features are something that will enhance your astronomy and astrophotography experience.
