...But if you do buy a cheap potentiometer, or actually, most potentiometers (but cheap ones mostly). Even though they rotate at 270 degrees, don't expect to get all 270 degrees of data from it. Cheap ones get probably 200 degrees of reliable data. Decent 270 degree ones maybe a little more.
My point: don't get a potentiometer that will just have enough rotation to work. It won't.
