A German seller on eBay has two slightly defective (small scratches/ dents) ones left. For $23 plus shipping I decided to go for it. Won't arrive for quite a while so I can't comment on the actual quality but thought I'd throw a post here for anyone else that might be interested.
However, this user does have one in "new" condition for a little more.
