I bought T2i from him. It was advertised as brand new kit but without the lens. Great price and transaction went very smooth. He shipped fast, replied to emails quickly, and it was just as described so I was very happy with the purchase. However, I emailed him a few weeks later asking if he is an authorized re-seller and can provide me with some proof of purchase for warranty purposes (since he advertised full US warranty in the auction) and never heard from him. I am not sure if one can get warranty service without proof of purchase from an authorized dealer, which I don't believe he is. I sold my T2i and got 60D instead so it never was an issue for me, but I wonder what would happen if I would need warranty service done on the camera purchased from that seller.
