Will, I am probably newer to the world of BP's & snakes in general than you are. I would have to say that an AlexHue or Dan & Collette over at BallPython.com would be a couple of good places to look. Those are two VERY reputable breeders & although you would pay more, what you ask for is gunna be what you get.
I am not trying to tell you how to spend your money since someone already tried to do that to me. All I can tell ya is that investing in a Het is a huge deal, especially since i know you plan to breed BP's. So I would say that paying the extra scratch is the way to go in this situation. Just my double pennies, but I thought I would break it down for you like that!
