I have just recently picked up a used Peak vise after looking at them for most of the last year. I also use a Renzetti traveller. I wanted something a little bigger because I mainly tie deerhair bass flies and I wanted something that had a larger surface to support my left hand. I love this vise, but like JC said, the plastic screw needed to be adjusted often. This model that I have is the original design, and may be different from what is available now, for I was able to order a replacement screw that was made of brass, and it works fine. GREAT VISE!!
