Those are going to cost you an arm and a leg literally. Doni just sold off the last of what she had and they went quicker then you could even access the site and weren't cheap and that was for juveniles. My guess is at least a couple of thousand.
Just be careful from who you buy your snowcasso from, make sure the lineage is to Doni. Get prof of purchase, some are selling Picasso as snowcasso. Just my 2 cents. There's is a tread on FB breeding about the current owner who bought the TM. Be careful we spent too much money in this hobby, to get disappointed.
