so is it a pair of adult leachies that you are looking at? whatever you choose i think should be at least a pair so that you do have the definite option to breed them.

which do you like better--pythons or boas?

like jballpython said, don't get the pastel unless that is a morph that you really like. save your $ for a morph you really really like and want to reproduce. if you get a het albino female you should also get a het male to go with her, as it would be a waste to breed her to a normal male. then you could also produce albinos your first season that they breed. but again, only choose the hets if you really love and want albinos.
