I'm putting together an 8 channel wireless rig, and looking for suggestions to control costs. I certainly don't want junk, but budget is limited to about $300/channel. I've seen quite a few of those OSP countryman E6 clones around. Does anyone have experience with these? Or other suggestions for less expensive headsets? This is for local theatre musicals, so sound quality is important. As for the wireless rig itself, I'm hoping to be able to pick up some used gear. Any wireless gurus wanna share their experience with what I should watch out for? Thanks.
