I've had my fill of playing with patch chords and am seriously considering the wireless option. I play lead guitar and vocals in my band and need to be able to move around and back off the mic at times. I did a little bit of research on wireless systems and thought the Samson Airline product looked promising. Its not as "hi-tech" as some of the Shure systems but its relatively cheap, $300 US. I just worry about interference and signal integrity. If anyone else out there could advise me on the way to go your help would be much appreciated.

Thanks
