You will never get above 2 bitcoins for this thing, let alone the 6.25 your asking.  Antminers, although currently out of stock, can be bought through secondary sources for a fraction of your asking price.

Btw, your pictures prove nothing besides that you had an empty box laying around.  Post pictures of the actual unit, with a time stamp, and your username written on a piece of paper.

If you do not want to post a picture of the unit opened up (I do understand that feeling) then I will offer 1.7 Btc shipped to 66221 payable once I receive the unit and make sure it works.

Edit: Just went to BFL website, and they are selling for about $4200 straight from them, which is about 5.5 btc, why are you charging more than the original purchase price?
