Ive seen an avatar here at ball-pythons that shows a blue pieball ball python. But could not find an related morph elsewhere

Are these snakes even real? I did a quick google and searched this site to no avail.

If i wanted to purchase these blue piebald balls, are they even for sale to most people or are they still too uncommon? Also what would i expect to pay for one? I am thinking at least $2500.

I would be in great debt if someone could give me a better place to find info on these blue piebalds... A link would be great.

I am looking for places to buy them and prices.
Maybe some genetic info would be nice too... just basic info about them
