it depends check evogear, they sometimes have good deals, 150 for p12 jibs was alright on their ebay store. id say go ebay, you'll find a deal on there, i got some p12s new for 64 last week so just try.
sometimes you'll find rediculous deals on bindings. I got a pair of axial 140s for 55 shipped because they were missing a toe slider. I got a replacement for free, whihc was uber sweet. Look at the skis on ebay that come w/ bindings. Alot of the time a seller won't know how much the bindings are worth and give u a steal
