Lots of places to pick up bindings:eBay - new, used and also look at worn skis which sell for under $75. They might include great bindings for a fraction of the real value
This is the time to look in ski shops for 2009 season bindings $110
Shop employees might sell their personal gear as they may have just purchased new 2012 equipment.
Rule of thumb, used gear should be 50% of the retail price.
I have purchased new on eBay for 40% of the retail price. Usually when the auction finishes at midnight or later.
