Samson Micro 32 Wireless (~$350-500)

I used two sets of these for several years after giving up on Azdens and before springing for the Sennheiser G2s. Sound quality, transmission range, and other features are decent for the price, and you can select from   several bands and frequencies if you get interference. Unfortunately these appear to have been discontinued, but the smaller "airline" series is still available and also works adequately.
