Has anybody ever fitted electronic cruise control? not the throttle friction type, but full automatic cruise control. I am slightly attracted to the idea and am looking for any input from folks with actual experience of these. I currently use a 'Vista Cruise' throttle friction type which is helpful on an essentially level, low traffic road, but he idea of a 'set and forget' system with a 'resume' button does have considerable appeal on 'Iron Butt' (Iron Brain?), type rides.
