Think about what you want to produce, whether in the long run, or right now. Look at the current designer morphs, and decide which is your favorite, then go out and buy the best ingredients!

People will tell you to get "quality" which means go for whatever YOU think is the best representation for the morph. You can also go for whatever looks unique and cool to YOU.

How many snakes are you looking to purchase? Do you have enough space for them? Do you have a source to get both frozen AND live rodents of various sizes? I found this to be a huge problem for me when I first got started, and I don't see this question being asked to too many people.
