Ed, I am a serious whistle player and have blown more than a little money on "high end" whistles. This summer I bought a another one from Pat O'Riordan who is the Stradivarius of whistle makers. I mentioned that of the inexpensive whistles, I like the Waltons/Soodlums mello D the best. Pat immediately agreed and said the mello D is the whistle he starts new players on. An endorsation by O'Riordan is the best expert opinion one can have. They are easily found, Elderly's for example. The Chiff and Fipple, sorry do not have the web site handy but search engine will find it quick enough, has reviews of all the whistles from inexpensive to very expensive. Whistles are the only instrument I know where inexpensive is often good. The Clarke Sweettone is often good also: the mouthpiece was designed by high end whistle maker, Copeland. The Sweettone is easy to learn on. The original Clarke is a lousy whistle.
