My recommendation as a Nevo and Pronto dealer. Sell the Q50, buy a TSU9400, and use WiFi. In this realm, you'll only be limited by the range of your WLAN. I just replaced three Q50s with 9400s because of the communication problems. I really like the Nevo gear, but think that they have some work to do on the wireless portion of the Q50.
And buyer beware of a man who chooses to be judged by numbers and salary, with no regard for character or integrity. Peter Gammons, ESPN
