Roger, I saw the Jointmaker Pro demonstrated at one of the Woodworking in America shows some years ago. It's a neat idea and I was impressed. After I thought about it for a while, I decided that, If you know how to use your hand saws, it's a waste of money. Hand tool skills are very versatile. You can make accurate challenging cuts with you back saw that you could never accomplish with this gizmo. Plus you can carry your saw around in your tool box.
