The Japan only model is not cheap. For that price, I think I would prefer the GW 5000. Obviously not CF, but a sweet DLC coated screwback and some sort of rubber/silicone strap. More comfortable than the basic polyurethane.

If the CF model goes international, the price will drop to something more reasonable.
