I did a search, but here's the issue: Most of them IEM thread discuss the BUDS, not the actual IEM unit itself. I've already got a great set of buds, UE Triplefi 10's, that I bought to use through my church's Aviom system. But what about the actual IEM unit? Which is the best buy for the money? I've been checking out the Carvin unit, because I own a bunch of Carvin gear, and the price is decent. Any others?
