$400 is a fair price..... I paid for one only 3 months ago, YES OFF EBAY!, for right on that mark including postage, received it within a couple of days, exactly as per your model, brand new in box in perfect working order.
Nothing wrong with ebay, just like the forums here you've gotta trust the person you're dealing with!
Good luck with the sale, $400 is a good price, so a BUMP for you!
