Over the last 30 years I have owned several vises, cheap ones in the beginning of course, but since 3 years I use a Renzetti presentation 2000, and to be honest, I will never ever buy another one.
The Renzetti traveller is lots cheaper, and the quality of the jaws is equal to the xpensive types.
Can only recommend it, for what it's worth....
All the best from Holland,
Hans
