I purchased that exact same model about six months ago when some guys over on the mbz.org diesel list were raving about them. At the time there was a "Buy It Now" price offered on Ebay for ~$120, so I think about 6 or 7 of us picked them up. Sad to say, I haven't found time to test mine out yet, but I do have a box full of dull bits waiting in my shop.
