A friend pointed me in the direction of the HMH vises. I like the looks of them (haven't used one yet), as you can adjust the angle of the jaws. I have used a renzetti one (not sure of the model) but found the angle, and how the jaws were quite low, to be quite difficult. These vices look good and are reasonably priced. May be worth checking out. You can check those vises out at: http://hmhvises.com/spartan.html
