I Have the DeWalt version and LOVE it! It cuts cleanly, leaves a very small burr (if at all), and cuts fast-as far as Blades (they are 14"), I've looked around and found them for under $100 (look at your local Metal Supplier)-I've also heard you can have the blades re-sharpened relatively cheaply. In addition to a hold-down, it comes with a sort of Vise grip type of clamp, which I learned you had better use on smaller stuff, but overall, I think you will like it-
