Mostly Crested Geckos and Ball Pythons from the breeders I checked out on the page--and I checked out all of them with a link. I did inquire about whether one of the breeders sells P. Laticauda, but not sure when s/he'll get back to me....
I know that BP morphs and Cresties are the popular and big money makers at those shows (along with poison dart frogs, it seems), but I wish more breeders would offer more varieties of critters for sale. Since I don't buy BPs or Cresties (I like black milk snakes, aberrant pattern california kingsnakes, and rainbow boas), it isn't really worth the entrance fee for me to visit these reptile expos anymore.
