Morph males are generally less expensive. If you do plan to breed and get a morph female, then perhaps picking up a co-dom or dom male would really spice up the project. Just by adding some pastel into any morph female would make things better I would think. But remember, breeding does require you to invest alot of time and money. So it really depends on your budget.
To me, there is nothing wrong or "not worth it" about breeding a pair of normals. Just look around and check for availability. There is always someone willing to buy a normal ball as a pet. It really is a great experience to hatch out your own snakes. Normals are snakes too and they do make great pets
