I'm not going to tell you what to get as your first ball python morph. Just pick your favorite, even if you have to save awhile to get it, I saved for three years to get the snakes that I have. Get your favorite, and breed for what you want, not what is most popular, or most commonly sold. Trust me, if you are breeding for everyone but yourself, you won't enjoy the hobby as much as if you were doing it for you.
