From what I've seen, the prices are kind of all over the place. I think it has a lot to do with how variable they are. Prettier ones are priced higher, I would guess, but I don't always agree that the higher priced ones are the prettiest ones.
At the moment, I see prices on KS that range from $55 for a female that looks pretty much like a Pueblan instead of a hybrid to $135 for a female that is mostly all black to $175 for a male that has a stripe down his back and is also het hypo. Personally, my favorite is a male with a stripe down his back that is $65.
