I still hunt with my Black Knight that i have owned for the past 15 years. It was around 250 new back then. I have since bought the Advantage Camo pattern in the same gun as a back up for 50.00 without a scope. I would say anywhere from 50.00 to 150.00 depending on what you get with it, would be a good deal. Ask for the "extra's" if he is trying to get rid of it. he had to have powder/pyrodex, bullets, sabots, bullet starters, powder holder, inline capper etc....
