I have the powertrax locker in my 97 rodeo. doesn't chatter on corners, isn't nosy, but you will learn to make changes in your driving style that are not a big deal to help keep it disengaging cleanly and noiselessly. It is the real shit off road, period. and I do mean period. absolutely no fail engagement.
coming into a corner you ease off the accelerator and coast into the turn. there is an occasional clunk as it disengages if you don't make the small changes to how you do stuff. it is not a hassle and again, definitely worth it. and it is very cheap, I mean price, not quality/performance.
I got tons of use from it out in the deserts of california and on the beaches and hills of mexico.
if you have lots of loot, though, the eaton electric locker or the arb lockers definitely give you an off versus on solution. I believe one version even has the in between LS possibility, all selectable.
