I'd try for about 75.00 if its in good condition. If less than good condition, I'd look for a different bow. If its in really good condition, and I KNEW it was in good condition, I'd probably go up to 150.00. They're easy enough to find if you watch eBay. I had one that shot real well, but as old as it was, it couldn't handle my 30" draw. After about 500 shots in my hands, it blew. Mine was a 709 Hunter and built in '67.
Take a look here.
