more than a half turn is unusual? That's not been my experience...
Go to Digikey, and put in your search terms on their
potentiometer page. You can get anything from 230 degrees to 3600 degrees rotation, including continuous turn pots.
Personally, I look at what we need for the application, add a bit for safety (no sense breaking it by trying to turn it too far), and order what we need.
