The Blaho brothers at Neversummer do them custom on a per order base. They are built from the ground up, but you got to place your order. Right now they are doing them for $1400. Which is what I paid for my Summit Split 2 years ago. They also come with everything. Full length skins, interface, and crampons. You can find Bentley Blaho at Splitboard.com or just email Neversummer and they should be able to hook you up. It takes about 6 weeks from when your order is placed until you get the board.
They do custom graphics, and that sort of thing. So your board can very much be a one of a kind.
