x4! Usually ball pythons have the same type of personality across the board - 90% of the time they're placid, calm creatures. If you're worried about one being aggressive, just email the breeder and ask. Hatchlings can be nippy because you're very, very big and they're very, very small and you're a predator in their tiny minds. The first week or so they're going to be stressed no matter where you get the snake so I wouldn't worry about them being too stressed if you have them shipped.

I would go with a PVC enclosure instead of a tank. Tanks are very hard to keep steady and if you don't have the perfect ambient temps, it's hard to keep a tub warm enough. PVC cages are the perfect balance even though they are the most expensive choice.
