my dad is the manufacturers representive for Fein PowerTools in the NW, and theyve got a new division called Grit that makes the easiest and highest quality tube notchers and belt grinders. We've already have sold some to Trailready, and talking to S&N about them getting some. Take a look at the website and products and let me know what you guys think
