Kevin, thanks for finding that pot. DigiKey shows it as "1 turn", so I had not found it. But in the Bourne link, it's clear that it is continuous rotation and would serve as well as the Piher part. Too bad it costs 4x the Piher one.
My concern about encoders was the CPU utilization, though I didn't much more than guess about this issue. Any estimates what it will take to track an encoder that reads 128 or better pulses per rev?
