Well, there's a couple reasons...
1. I'm a college student with no time for a job, so I won't have any money to pay for the snake, let alone the proper setup until summer.
2. I live in a dormitory, and its hard enough to hide one snake in your room, let along two. I currently have a 5 month old Kenyan Sand Boa who is happily residing under my bed. I can't wait until I graduate and can own whatever I want, provided I have space and time to care for them.
3. I've had my eye on the classifieds, and on stock shops since I first discovered the ball morphs. I'm not seeing any idividuals that are to die for, so I'm hoping one of the new hatchlings will catch my eye.
Or maybe I need to wait a year and save the cash for a morph. Thats what I really like. Oh wait, I'm going to grad school... I seriously need to find a less expensive hobby.
