I don't find the prices to be outrageous at all. I'd pay for a few of those, if I currently had the money and capacity to take on new animals.

It IS a bit of a gamble, and not everyone is comfortable doing that...but there's nothing unfair about the prices, just because some people aren't comfortable with them. Better to have a greater chance of getting those babies into the hands of someone serious about proving them out...than letting them go to just any pet owner who has no incentive to breed them.
