Mujitsu and Tairaku's Shakuhachi BBQ

I've been vaguely familiar with the shakuhachi for some time but only considered learning it a few days ago. I tend to join forums for all my interests, apparently. I've attempted to make a 2.0 from PVC and I've gone from only being able to play Ro to being able to get a few notes (no fingers covered is still tough). The only instruments I've played are guitar, bass, and a little keyboard. Using my mouth and lungs is a totally new experience. Even from yesterday, when I felt dizzy after a few minutes, I think I feel my lung power improving...

I hope to order a basic level bamboo model within a week or so. I have no access to lessons here and this would primarily be for personal use and some recording.
