Great report on Dyna-King.
I will add my story on how well the team of Gretchen and Al Beatty support the Danvise that they distribute. When I got my vise the instructional DVD did not work. They replaced it promptly based on my eMail message. Later I had a question about a "Clouser" configuration of the Danvise that I had seem on the web. My e-Mail got a prompt response that explained a simple no cost modification to achieve the effect. Not bad when you consider the cost of converting a standard Rensetti to Clouser mode. Drill a hole ahead of the existing slot.
Clouser Mode
Though I have never had the problem, I also understand that they do a good job of replacement should someone overtorque (Rensetti) the jaws and break them on a hook. Now, they won't get rich distributing $85 vises. But maybe they are rich already in a different sense.
