Barb, the "powertec" set up uses the "PC style" threaded base, and that will marry well with your DeWalt router. The one Mike Taylor is selling has the Bosch base, and will be fine on a bosch router, (rarer) than the PC style. All of these should be made to point out these differences, because the "sloppy" Bruce and Nathan are talking about is real, if you use the wrong "style" base. I have had all PC style for ages, and end up getting just routers that marry to that style, and don't have issues. If you start doing a lot of this, and want to upgrade to the Whiteside it's PC style. It used to be right away they would say PC style, then Bosch wanted to be??? different??? Anyhow I steer clear of their stuff just because it seemed at first they are the ones wanted to be different, they sure aren't any better. Now hardly anyone wants to point it out, and a lot of folks don't know they are 2 very close sizes, but are different. BTW Leigh is PC style, and having a PC style router will allow much better fit with all of their jigs too.
