As others have said go with the nicest of the two, or if the extra money will put a hurting on your wallet/bank account than get the one you can afford. I have seen youtube videos and forum posts of males breeding as small as 100-150 grams. There is no guarantee that an animal will breed, be it a proven breeder or a non proven breeder. I'm going to steal an old fishing saying to say this. It is called breeding not hatching. Don't count your chickens (ball pythons) until they hatch.
