I'm designing a front panel for a radio, and I'm curious about opinions on rotary encoder dials. Some dials feel cheap, some feel rugged, some make me feel almost inappropriately gleeful in the turning-this-dial-shouldn't-be-this-awesome kind of way. There are two components at play here, the hidden encoder piece that controls the feel of the motion and the physical cover that your fingers touch. I'm interested in opinions on both. What dials do you prefer and why? What made them feel good to you? What radios would you want to steal dials from if you could pick and choose?
