I came across one of these today and I am bit interested. Anyone have any experience with them and if so was it positive? Any advantage this would have over a traditional router set up? I can't quite get my brain wrapped around it. Does it attach to any table saw like a typical dado set? The one I came across was similar to the one on ebay and not on youtube.
