Hi I've got a Nikon Fieldscope 25-75x82 ED with zoom eyepiece that I'm thinking of selling. I have no idea as to the value. I can't remember what I paid for it but well over $1000. I bought it a probably 10 years ago and just never used it very much. It is in perfect condition. Comes with the original softcover, Vanguard Lite tripod and a locking hard case. Any idea what value I should place on it? Should I put it on GunBroker and let the market determine the value?
