I can't recommend anything in that low price range, but I can tell you NOT to go cheap on wireless gear. Like anything else, you get what you pay. I work in television and all of my wireless gear, since I started freelancing in the 90's, is Lectrosonics and it's the majority of what you will see in the field being used professionally(for a reason). Audio, unfortunately, is an afterthought a lot of times. It's not "sexy" like a camera or lens, but it is just as important. Lectro gear is not cheap. For someone with my needs, you are looking at about $7K or so for a complete two-channel system. But they have "entry level" systems, too. You can get into a single channel set-up for under $1,500. You are much better off spending a little more on an entry level Lectro system that is built to last than a plastic Azden or Sennheiser or Shure system that's in the "$600" range.
