This track saw is well known as a quality product and i saw this NIB saw on eBay. Buying it was an easy decision. Several manufacturers make track saws. I don't know how good they are, but this DeWalt saw is a winner. It produces a flawless, accurate cut and by stringing together tracks you can make the cut as long as you need. It is powerful so you don't have to be worried about bogging down. It has a riving knife as well. As is obvious, I'm a fan of this saw.
