I would definitely pay through Paypal and make him send you an invoice through them so you have some form of recourse if it goes south. Or maybe pay with a credit card and if he doesn't deliver, call the card company and do a chargeback. His BOI seems fairly legit. From just glancing at, it seems he also sells third party snakes as well so not all are his own. I say go for broke and go for clown pieds!!!
