List it privately or consign it at your LGS for $450. It should find its new owner quickly enough. Keep in mind if consigned, you'll probably leave $50 or so with the dealer...which seems fair enough for a low effort transaction.
All of this is assuming it's a "like new" Gen3...just an educated guess on my part. So if it's made of cast iron or smells like hot dogs, disregard my appraisal.
