As was said in the other post there is a greater market and greater want for ball pytons than Burms. The number of morphed balls is staggering in compairson to the burms and retics. I mean theres probaly more than 5000 different proven combos in the ball trade now! Not including the stuff that people like VPI, NERD, RDK and so on haven't even let out yet. Pick an animal that you enjoy working with and that you like forget the money for right now and get what you like and go from there. Wether it Leopard geckos or Balls.
Just my two cents.
