I personally wouldn't bother buying snakes from "flippers" (people who buy and sell snakes to make a profit). They don't know the history of the animal and are usually only in it for the money. Who knows how they take care of their animals.
I would pass on the pastel male honestly. Save up for a pastel female if you want to work with the gene. Or a double gene of some sort. Double gene animals have been coming down in price recently. Not sure how the market is over there though.
