Right now the board designer has only made a small batch of prototype boards. He's thinking about a refreshed design and might take it to some sort of other funding platform, but as with all hardware projects, hard to tell what would happen or final price if it does happen. Look up the TOFU, by Oratek in Switzerland, for something relatively comparable.
