If you can afford the PX12 JIB I would highly recommend it. I consider bindings one of the most important parts of a setup, second only to boots. As has been mentioned, the PX will hold on longer, its got more elastic travel or something like that. If its set at a sane DIN your not going to tear anything, it just gives you the ability to be sketchy and not have to hike back up for your skis. About as legit as it gets, but I guess I'd take the low end Looks (or Rossis if you want to that route) over the low end sollys. Dont get me wrong some of the high end Salomon binders are legit but the low end stuff has a shit reputation and I'll back that up from personal experience. In the end you get what you pay for.
