Boylei's go for a cool 5k each, stateside that is. If you go to Japan and get them, if you can find them, it would cost you a lot less, till you try and get them here, customs would probably hit you with a hefty fee.
I want them too, waiting for someone to breed them successfully, then the price will come down, until then, I'll just look at the pic I have them and dream.
