If you're new to tying, I'd recommend tying on a number of different vises to get a feel for what you like/want. Also, talk to others and ask what they use, and why. You may discover a feature or drawback that you didn't realize. For instance, many people buy a true rotary, but never actually use that feature.
Fwiw, I don't like the jaw design that Renzetti and Peak have, but that's because I tie mostly small flies. If I tied a lot of streamers or used the rotary function, I would've kept the Peak I had.
As far as prices, most features/ styles are available near or below the $300 range. More than that, and I'd assume it's a vise for show, or something very collectible like a LAW vise.
