I would get a lot of triple/double co-dominant or recessive animals with some of the nicer basic morphs like Lesser, Mojave, Pastel, Cinny/Black Pastel, Albino, Hypo, Spider, Pinstripe or even Pied. Then I would get one or two more expensive animals that would add expense to the collection, which all depends on you.
CB-70 racks won't hold hatchlings too well, but would work well for breeders. I don't know if you want to try to buy adults or younger animals.
