Great mill. At least you don't need too much air to work with wood. Get the Venturi version. Instead of bags, Venturi allows me to use a 4ft open-ended hose that lets sawdust fall to the floor (which I vacuum daily) without throwing it up in the air. I don't have to run the vacuum or even wear a mask when using this grinder. It's pricey, but a good example of "you get what you pay for".
