Well, pretty mutch with a budget of $200 that dosn't give u a lot of options other than the Maculosus, stimpsons, and childrens pythons and that's if you get them from a breeder as most pet shops sell them for $280 +. I agree that childrens, Macs etc are a lot more snappy and it proberbly is due to there size (always felling threatend). All I can sugest is with any snake u ever get, try to go for one that dosn't snap at u the first time you pick it up and go for a known breeder. Baby bites don't hurt (more shock than anything) but it can be enough to make u nervous and this leading to a nervous snake. Just look around and see if you can find a breeder that will let you have a look at the babies and parents and I sugest see how you go handling both, make sure you can also properly care for the snake as well before purchasing (keep in mind all animals could possibly need a vet at some stage and it can cost big $$). Not trying to put u off or anything but just keep all this in mind before you make a decision.
