I don't breed yet, but I'd say don't get any normal females if you can afford good single-gene morph females. Normals can be hard to sell, so consider that... Also consider that a normal costs just as much to feed / house as a morph.

I would suggest going to a show and seeing what you can find in your price range. I am sorta in the same boat as you.. I am not certain that I want to breed yet, but am going to be purchasing all females to start and only getting morphs that I like (so that I can enjoy them as pets as well as potential breeders). I was pretty lucky and picked up a pastave female at a show for $250... So she is a 2-gene animal and will give me lots of options should I decide to breed her.

Given that you already know you will be working with recessive animals (pieds), I'd suggest trying to find some morph females that are also het pied. Also check out currently produced pied combos and see which ones you like and purchase morphs based on that.
