I got some literature on Rainsong guitars a couple of years ago. They looked interesting and I'd like to try one, but they were way beyond my price range. As I remember from my days of working for an engineering company, the tooling and equipment to make things out of graphite composite has to be precise and is fairly expensive, and as far as I know this is still the case. So I'd expect, at least as far as good-quality guitars go, any graphite composite guitar would be fairly expensive. Hmmm...with a Rainsong guitar and Elixir strings you might well be able to play under water. A whole new genre!
