There is a guy in Oklahoma that breeds. Constrictors.com He might be a little expensive, but all of his snakes look really nice. Also check around. The is a Texas Reptiles forum, and a woman in Spring Texas is selling a yellowbelly male, she also has a breeding age pastel pair that is REALLY affordable. I also found a girl that is willing to let me borrow her spider to breed to my super pastel when I'm ready.

good luck! I'd get a bumblebee if you can afford it, a lot of fun color combos can come out of that.
