I have both a DynaKing and a Renzetti. Both work well but I find myself using the DynaKing more. I think each vise will have its followers. I'd develop a list of requirements of what you want in a vise before going to purchase one. List things like price, durability, portability, griping action, expect length of use and accessories. Go to a local fly shop and "try" several of the vises side by side for the "feel" of the vise. A lower end vice may only last a few years vs. one like a DynaKing that is built to last a lifetime.
