If this was the case then Burton would make the best bindings, they definitely are not the cheapest.
That said they do make some good bindings, you cant discount them all.
true, alot of them are way freaking expensive, but to contradict what i said before, just because a binding is high priced, doesn't mean it is a good binding. But the lower end of burtons bindings, i.e freestyles and customs are absolute crap. So in a way you get what you pay for, but not always the case.
