... would be best for an adult ball python? I've heard good things about the Animal Plastics cages and their suitability for snakes, so I'm considering adding it to my snake wish list. Different cage sizes are different prices, so which do I go for?

I want a nice looking enclosure for my snake, whenever I can finally get one! My thought was to start one in a tub if I get a juvenile and then move them into a cage like an Animal Plastics or Boaphile once they're big enough. I get an adult, it just goes straight to the cage. Bad idea? Good idea? Thoughts are appreciated.
