Having done all those types of cuts with a router, I had never used a dado set before. After having read all the reviews, I sprung for the Super Dado. I have nothing to compare it to, but the results were just amazing! I was test fitting a joint after my first cut and it was so perfect I wondered if it needed glue. The set up/sizing chart it comes with is dead on, but just in case it comes with shims. None of the chippers are marked with their sizes so you have to look carefully at an edge(or measure, but there are only three sizes.) I highly recommend it!
