Salty, I have a Freud biscuit jointer and a Craftsman BisKit adapter for one of my routers. The Craftsman adapter does a good job and addresses the safety issues Tom brought up; the cutter is covered with a plastic case to keep fingers away. The only drawback is you can't cut into the middle of the flat side of a board, only an edge. This device is the $40 solution to glueing up flat panels or boxes.(If you own a Craftsman router)
I got the Freud in a swap with a buddy, havent used it yet, so no opinion on it. Hopefully you will have located different brands and put hands on them to compare features before ordering one. Happy hunting!
