Vouch, sold him 5.4b and agreed to return if he didn't need it for his big trade. Even though the paypal payment reversed to him (paypal's intervention, not his), before returning the gold, he came through and I trust pockets.
Huge vouch for this man. He took time away from his day to help me build my own computer, and even went the extra meter to link me directly to parts. Very stellar fellow.
