Joe, preferences vary widely as to the best system to use. We are a bit prejudiced here towards the Router Workshop system from Oak Park. Bob and Rick's "simple is better" methods help you get the most from your time for the least outlay of money. None of the systems you mention use the larger Router Workshop style guide bushings, and this system allows for much more versatility than the PC style. Spend a few minutes reviewing the Router Workshop items at Oak Park and compare for your self. There is a link in the top right corner of this page under the button that says recommended stores. I would be interested in hearing your thoughts after comparing the Oak Park items to the others you mentioned. Welcome to the forums.
