I installed the Area 451 CC a while ago (okay, I got in everything EXCEPT the wire harness - didn't want to mess up the car's plug, so I had a Charlotte company do it - $50 and half and hour). The Area 451 is very simple - push the button to turn it on at present speed, tap the break or push the button to turn off. Granted - no resume or accel feature, but that's what I have a gas pedal for... I have no experience with the other, so I can't comment on better or worse, but I do love the one I have.
