Definitely get the morph you mostly want as a pet. Breeding purposes are different but as you stated, snake is going to be your pet. If you go for cheap one, you will regret. I have been considering that too when I first got my bp, my budget was under 100 dollar for basic morph. However, I went into the shop, saw the banana, spent 250 dollars on him. I am so happy I did it. Remember you will be keeping snake for long long time.
