Most folks don't get far enough off-road that requires any traction device. I've been places in a Datsun B210 that are just crazy. I know its blasphemy to say that stock is OK, but there is always someone who points a finger at anything less than an ARB locker as inadequate. I say if stock gets you there, then you are fine. If you find yourself getting stuck a lot, then consider upgrading to something that will get the job done. Dropping $2k for lockers that you'll never really need doesn't make sense. Spend the money on a well deserved vacation instead.
