I've had two Radial Arm Saws, a Craftsman, and a pre-war DeWalt. I agree with Lee that the Craftsman fell out of alignment pretty easy, to the point that I had a Allen T Wrench mounted on the wall next to the saw, and typically slacked the arm and used a framing square to square up the cuts weekly. It was pretty easy to align, about five minutes or less. The DeWalt is rock solid and is adjusted perhaps once a year.
