Thanks for the info, Muttley! Very helpful when I do finally get one. What about the ones made from pvc (plumbing) pipe? I've heard them played by some so-called experts, here, but are they harder to play?

Thanks, SRS, I'd seen this. Followed the link and found some indication that it was not as simple as at first it might seem, the testing I mean, but I am game to try anything, but CPAP! I also have been blowing my harmonica which has been shown to improve breathing, etc.

Thanks, Wolfgang, for this thread.
