If you don't plan on traveling much, we also may suggest that you look into the Audio Technica M2 – This system is the same audio and RF circuit as the M3 system, but with a more limited feature set. This system is tunable via 2 knobs versus being a digital readout. There is also no scan function for finding open frequencies. But, if you are staying in the same venue most of the time, this shouldn't be a problem. More info: http://www.audio-technica.com/…..index.html
