Here is a page that might helpYeah, I'd definitely go to an expo vs a pet store... at the very least, you are getting your snake from the breeder who you know cared for it and not from a pet store where you might be unsure. Plus, you can ask the breeder questions about your snake, caring for it, and feeding it and get some legit answers.
Good luck! I went to my first expo a couple of months ago and LOVED it!
