Analog potentiometer for use with dual motor contoller?

Pololu TReX Jr dual motor controller + 2 x 67:1 6V gearmotors. Can someone suggest an analog potentiometer for the above setup and where I can order one from?



All the usual electronics sources (Digi-Key, Mouser, Jameco, etc.) should have tons of potentiometers. Maybe even Radio Shack still carries some if you want a local store you can walk into. Something like 5k or 10k is best; beyond that, it’s mostly up to your physical/mechanical and aesthetic requirements. Oh, it should be a linear pot, not a logarithmic one.
