If you check eBay completed listings, $450 for this one seems excessive. There have been quite a few that went for much less than that, even with wood cases. If it's not too far for you, I'd show up, take a look, ask for a demo, and offer $300 unless it works perfectly. If you honestly want to pay $450 for a Marantz receiver, you can find a better one in AK's Barter Town.
