Seemed like a good system but I never was able to see or try one before they were discontinued. As Peter said, there are other dovetail jigs which perform well, like various Leigh models, Porter Cable Omnijig (if it's still sold). It really depends on what you want to do with dovetails. If you want to do just standard equally spaced dovetails, there are a lot of basic jigs available which I would guess all produce about the same result. Variable spaced dovetails, both through and blind, can be done well and easily with Leigh jigs. I now use an Incra table with the Incra positioner for my dovetails, both blind and through. It works great, is very accurate, and relatively easy setup and execute.
