Balls and corns are both excellent snakes. Depends on what you like better. Other things to consider are the many other colubrid species and other small snakes such as kingsnakes, (california and mexican black kings are very cool) milksnakes, (pueblan, honduran, and sinaloan milks are all gorgeous) hognose snakes, (definitely unique looking) sand boas (kenyans are quite lovely and unique little boas).. and many more. Often these snakes have inexpensive morphs.. such as albino and anery.
