Are you planning on breeding? If so, I'd spend as much as you can on the next snake to get some higher end snakes in your breeding program, the more you spend the more you will break even or make a little money. If not, I'd go for the brightest colors. I really like the fire / pastel mix, very bright yellow. I really like the Axanthics and the Ultramels myself, may pick up some of those myself. How much do you have to spend?
I'm actually just starting out breeding ball pythons. I have six snakes so far and spent about $4,000. I think you'd be better off with just a couple high end snakes, breeding those in a few years, then use that money to buy whatever your heart desires.
I might eventually so it's something i am taking into consideration along with my own personal preferences .
i have about 200-250. total.
I was just told not to tell them what i decide on as they are planning 2 for christmas this year sometimes family is good =]
