Has anyone used the Marc Sommerfeld Tongue and Groove system? I emailed a query to the company about what made it better/stronger/worth the extra time compared to employing only the pocket hole joinery it uses and received a reply suggesting I either catch their show demo or buy their $15 videotape on cabinetmaking.
I'm not thrilled to pay $15 to view an infomercial. I'm sure it's a quality product and all, I've purchased other Sommerfeld router bit kits, but there are many quality products that do not solve problems in a universal way. I read the few paragraphs selling this system on the web site but still don't get WHY a person would use it, what superiority it gives to the cabinet project.
Any hints, tips, war stories gratefully solicited --
