If you're looking for a Wincher style bumper, then these are the guys to go to:

They make a real solid product and its half the price of the ARB. It weighs about 120lbs so its does sag about .5 - .75 inches with stock suspension. They can add just about anything you could need from d-rings to a full on PIAA light package. I highly recommend them and I'm not quite sure why they haven't done a better job of marketing themselves with such a great deal. The only thing I would have done differently is have the spray on bedliner coating from the start.
