I was able to successfully build my wavebubble using these boards. You should note that the silkscreen is not correct (this is noted in the errata pages on the WB Wiki). I referenced the eagle files and part layout sheets extensively so it did not matter to me if the silkscreen was off.
This project was by far the most complicated one I have ever done and I dont dare think about what I spent on it by the time I was done. It also happens to be one of my favorite projects and it was very satisfying to build.
