or send the potential buyer the SN, you can then check to see what components are are in the machine. If he would supply me with the SN, thats all the verification I would need. he doesn't need to publicly display the numbers but If Im going to get it anyways, why not give it to me? I just checked my SN and it tells me exactly whats in my machine and the date of manufacture. A picture would be nice too of the SN from the box with his username like he did with the boxes and the pictures. I would bet he wold sell out within a day if 1. he takes escrow and 2. can prove that he has is legitimate..
