Since AT just replaced the U100 wireless with the 1800 series dual channels, I found pretty good deals on the U100s. They're true-diversity and have TA5 plugs on the transmitters so the lavs wouldn't need to be re-wired on the step up to lectro. Has anybody had any experience with these, good or bad? Being in the same price range as the G2 with diversity and a metal chassis, seems good on paper.
