If you are going to spend that much on a binding, it is worth it to get a pair of FKS 155's / 185's. They aren't terribly hard to find if you have the money and I honestly haven't heard of them having problems before. My friend has 6 pair and I have 2. All of them are in the same condition as we got them in years ago. I don't understand why such a bombproof binding was discontinued.
If you want to spend $329 on a binding, get one that is unanimously bombproof. Salomon 916, FKS, P18, etc. Go with something that has overwhelming feedback. If you want to buy your bindings because they look cool, go with Jesters. Other than that I don't see why anyone pays so much for them when there are perfectly good alternative for much less money.
