IMO, the Arsenals are the best bang for your buck in terms of freeride bindings. Decent adjustability, excellent toe cap and great ratchets for an incredible price. I'm not too sure what quality issues tekniq is referring to, but my Targas have seen two seasons of riding and they're still functioning like new.
My experience with the NRC's are limited, but I thought them to be great binders as well but a little softer than the Arsenals and a bit more expensive.
To be honest, you can't go wrong with either.
