Like Nate said, check the BOI to see if there is a thread about the breeder of the snake you like. If not, start an inquiry thread over there, and also on here. If you get good feedback, call the seller, or email him asking him to call you back, so you can get a feel for his customer service and how he cares for his animals. If you get bad feed back, or even if it's mostly good, but he takes too long to get back to you, or you get any bad feelings, move on to another snake from a different breeder and start the process over.

There are plenty of great breeders out there, so there's no reason to buy from anyone who has a bad reputation, or who lacks in customer service. The BP market is truly a buyer's market when it comes to being picky about who you deal with, no matter how big or small the breeder is. There are plenty of good guys, and plenty of shady characters that use kingsnake, so when you find a snake you like, do your homework. It will pay off.

*I know there are plenty of women breeders out there, I only used the words 'he' and 'him' in this post because 'their' is incorrect, and I don't like typing out he/she every time. No offense to the ladies out there.
