I agree with Tigergenesis, that Kings or Corns are an easier-to-care-for first snake. However, it's also really important to think about what you really want in a snake. If you're not really going to enjoy keeping a corn, no point in buying it to see if you like keeping snakes, then getting the one you really wanted. Balls are harder to care for, but if that's what you're looking for in a snake, it might be better for you to concentrate your energy on the more difficult care for a ball, than to end up with 2 snakes, and you're not that interested in one of them.
Anyways, I'm not sure if this makes sense, but I think the most important thing is to find the animal you REALLY want, learn all you can about its care, then decide if you can provide that care. If you can, then at that point, buy the equipment needed, set it up, and then buy the animal.
Hope this helps...
