The Sky-Watcher NEQ3 Pro is an excellent and economical mount that can handle a wide variety of telescope optical tubes. We commonly mount 80mm (3.1") to 203mm (8") optical tubes and they hold solidly.

These mounts now include the add-on GPS sensor module to automatically set your time, date, longitude and latitude based on the Global Positioning Satellites orbiting the Earth.

You can also plug this GPS receiver into your PC's USB port to add geo location capabilities. One possible use is contributing to the Open Street Mapping project.
