I got my Camo ones from Neiman Marcus here in Las Vegas, that was back in November the day before Thanksgiving and they were $645.00 retail...the SA told me that it was their second shipment of them in...they do run true to size if you do decide to purchase them...their great shoes, you will be very happy with them...they are so much more beautiful in person!
I'm am also looking for some silver ones but the only ones i have been able to find is a few overpriced ones on eBay, and like you, I would rather not buy off there because of them being overpriced..
