I vote for the detroit also. Mine is around a year and a half old and its just there, no locking it, no breakage no hassles. If not for the clicking on tight turns it would be invsible on the street and its irreplaceable on the trail. Oh, by the way I went wheelin' at Tellico with two jeep rubicons and they have the electric lockers and one of the guys must have snaged something underneath because his front locker quit about half way through the trip. I know this was probably rare and nothing is fool proof but it is one more thing that can go wrong. I also HEAR of cable, air hose and wire failures but its hits home more when you see it first hand.
