I got a Powermaster Ultra Torque from Advance Auto back before Thanksgiving. Cost me $150. They had a special where if ya spend over $150 ya got 20% off plus another $50 for ordering online. I think it was part number PM9050, but you'll have to call Powermaster and have them ship you the adapter to make it a PM9051 so it will fit a Super Duty. They shipped mine for free.
