Thinking of upgrading my trolling motor to autopilot, because I'm getting old and lazy, but it's hard to justify the expense. My Riptide 101 lb thrust was new in 2008, had a new board installed last year, in excellent shape, runs great, 36V hand controlled and long 60" shaft. If I can get $500 I'm going to upgrade, which is a good price as new are close to $1100.
