Most people don't plan on breeding normals, it's usually a side product of the pairing. The more genes in the mix the lower the odds, but if you breed a couple single gene co-dominant morphs together you'll still get 25% normals. For example, this is the result of crossing a pastel with a pinstripe:
Percent Fraction Genes 25 % 1/4 Normal (Wild Type, Classic) 25 % 1/4 Pastel (Pastel Jungle) 25 % 1/4 Pinstripe (pin) 25 % 1/4 Lemon Blast
I have quite a few double or single gene females and single gene males so will get quite a few normals this year. I have a local pet store that will buy as many normals as I can give him for $15 each, he marks them up and sells them for $50, and I think our local Petco sells them for $80. At the shows the cheapest price is typically $20. Craig's List is a good place to get cheap or free snakes, I have a nice big beautiful normal female that I got for free on CL, she is breeding this year for the first time. I'm actually breeding her with a scaleless head male, hoping to get a scaleless head female to raise up so I can eventually get a scaleless ball python.
Personally for your first snake I'd wait for a local reptile show like Repticon. You should be able to get a variety of choices from multiple breeders and pick up something nice.
