I have used this saw for two years now doing fine finish work on multimillion dollar homes at Lake Tahoe.  I work on a large crew of woodworkers and we have every saw ever used on the job. I have used them all. What sets the DeWalt apart is the large capacity and ease of use.  The saw did need calibration out of the box.  There are three nuts to calibrate the 0, 45 degree left  and 45 degree right stops.  After some fine adjustments it has been cutting perfect miters for years.  The fence was not perfectly square with the blade at first.  I calibrated the fence by removing it and filing the bolt holes to slot them a little with a rat tail file.  Since the first calibration it has performed flawlessly. The dust collection is make believe.
