To the OP - I took a look at the pastels that Garrick has available right now. Were I in the market for a male right now, the $175 one would be my first choice of the ones he has availabe, with the second one priced for $150 being my second choice. The $75 ones have the most potential, in my experience, to brown out as adults, and some have already begun to brown out.
That's the difference in the prices. If you plan to breed, and you want people to be interested in the animals that you produce, you want to start your foundation animals with the best examples that you can find.
