Shops here will price thier used #1's between $600-$650 usually. A few with nice optics get a bit more. I'd say for a decent one as you describe, $600 - $625. Hate to say it but a Bushnell won't bring much additional to the package. Last I looked my dealer could order me a new one and his cost was just under $700. Of course for a trade, expect considerably less as the dealer then has to be able to mark it up enough to make it worth his while while still keeping it at a reasonable selling price.
