I have a pair of 2009/10 Marker Duke bindings in very good condition - size large with wide brakes - DIN 6 - 16. I'm a teleskier-skinner and I used these with an alpine touring setup just to mix things up. Used no more than a half dozen times. In my opinion, the best alpine touring/skiing binding on the market.
This binding new is around $450 - check out backcountry.com/etc. The bindings are here at Sugarloaf. The first $225 takes them.
