i don't know of any that i'd say are junk.. the biggest difference that i know of, is how much they close. belisle's are gonna cost the most, but they close tight all the way..thats where you hear about beavers getting held by a tail.. dukes are the least expensive and work fine, but don't close all the way. most of my bodygrip trapping has been 110's for muskrats, so i've always just bought dukes.
