Be patient with your decision. I favor the locker over the winch, but only because of my experience with open diffs. and being stuck. If you do not have something reasonable to pull to, a winch may not help. Lockers can make you feel practically unstoppable. Once again, be patient. I found a Detroit locker on e-bay, got a lock right for the front (cheap), and bought a used Warn 8274 from a friend. All for not much more than you are budgeting. Patience was the reason I found what I wanted. If I were to do it all again, the only thing I would change is getting power steering before the front locker. Now it appears I am trying to develop Popeye arms when wheeling in 4 wheel drive.
Good luck!
