I did a google and not much comes up on this. Overpriced, poor quality, or just inadequate marketing?
I have a HarborFreight jig and it is hell to set up and use; though it does work with patience. The Woodhaven looks like the same principle only better made. Is it any easier to set up?
I am also interested in the Keller and box joint templates that are available for it. How are they?.
