.....SNARK SN-1 BLUE color on EBAY for $11 - $12 incl. shipping! Numerous sellers! Options incl. Tap Tempo Metronome, Transpose Feature, and Pitch Calibration (415 - 466 Hz) This dark blue model is very non reflective of light on your headstock so isn't very "noticeable". I've had one for a month and it is quality comparable to my much more expensive Intellitouch PT10 TUNER.
