Has anyone had any experience with the Shop Fox Dovetail Jig? It looks pretty good. It will make all the dovetails and box joints. I was also looking at the Oak Park Box Joint jigs. They make 3 which are 1/4", 3/8", and 1/2" using a router with straight bit. The Oak Park jig is about $56 for all three sizes. The Shop Fox I can get for about $87 with a 1/2" half blind, 1/2" dovetail, and 1/2" box joint jig. I would have to buy the guide bushings for my craftsman router. Just wondering if anyone could give me some info on each. Thanks.
