No expert but for 3 yr old bindings at $120 I feel that is ridiculous high.
NS board 3 yrs old for $200 you can almost get last years on clearance never used for that.
I find Craigslist usually quite high, you need to look for the good deals or meet the guy and make him a reasonable offer.
My gear sells very fast on CL as my prices are to sell not make money but to offset the next upgrade
