My vote would be for the Renzetti Traveler vise. I have the cam jaws and have not had a problem with mine so far. Have tied everything from 1/0 to 20s and the hook holding power is great. can bend the hook before getting any slippage. Also the rotary action is nice. Makes tying go a lot quicker.
Also at 150 I think it is quite the bargain. It also compacts very nicely to bring on the road with you.
