Well you have to consider a lot of factors when it comes to very high priced animals. Most breeders who even make the investment, have specific plans in mind and already know who their buyers would be. You don't jump in blindly and buy a $20,000 animal.
In most cases these people just a morph or genetic before anyone else, no matter the cost. But keep in mind most people only sell females if its a co dom or dominant gene and males are going to be twice the cost of a female.
They sell often, but a very limited quantity of animals are available. Let me know if you can find a male ChamPin For sale...
