I have used Marker M14 Comp bindings at home I bought from someone back in 2009. Havent used them though because I mounted my current skis with Rossignol Axial 12 (?) bindings.
How long do bindings generally last until you wouldnt use them anymore? I reckon they were used fairly often by their previous owner. Same question applies to the Rossignol bindings which held up fine so far.
