The "flood" usually happens a month before the daytona show or right after. Right after Daytona is when business slows down and prices on younger snakes get very low... Buyers market!
You could go with any of the "Big Breeders" but you might not get the best deal. But you will not get ripped off and you will get a quality animal. I also breed and carry all the animals you have listed... Adam at 8 ball pythons is also a favorite around here.
