Hmmm....you might be interested in Dale Wisely's comparison "between the tinwhistle, the recorder, and theNorelco Triple Rotary Head Electric Shaver ™."

In it he quite effectively points out the differences between these three devices....the most notably being that the recorder and the norelco shaver almost always sound crappy.
