Hey Guys, I saw a lot of posts in my search on wireless units and found out a few things, but much of it doesn't seem to be too relevant to what is available now. Basically, my understanding is that UHF signal is incredibly important as is frequency range (<30hz). So now, I need to find a unit that is good and readily available. I read a lot of good posts on the Sennheiser Digital 1000 series, but they aren't made anymore, so they're harder to come by. X-Wire, but thost are rare nowadays and overpriced if they are available... I also saw that some people are fans of the Shure UT14 and USX series. The USX series is more than I want to spend ($600 for a new one) right now. So, the question is, what's the best wireless unit on the market today, and then what is best for < $600?
