Nice little enchi male, I like him. Make sure you do research on any breeder. Kingsnake and faunaclassifieds both have feedback forums (KS has a feedback forum, right guys? It's late here...) where you can look up a breeder to find out their reputation.
BTW, here's that guy's BOI (Board of Inquiry) list: http://www.faunaclassifieds.com/foru...archid=3125299 Since it looks like he hasn't had any postings in a while I would work on getting a FC account and inquire on if anybody has done business with him recently.
Some breeders get their babies on F/T right out of the egg. It usually doesn't take much to switch a hatchling over to F/t mice or rats.
