you will get more of a rise out of the scalloped question in the bass section.
Honestly they may be cheap and seem affordable, but you get what you pay for. The 2 best wireless systems i have used to date is EV re2 or RE1 and the Sennheiser 100s 300s or 500s, they are all great sennheiser is a little more becuase you get a nice cast bodypack, but the Ev re1 comes with a cast 1 as well.
i think the RE2 is under $600 somewhere, very good bang for your buck. has an abs bodypack.
AKG wms 40 is also good if your still not sure you want to dive into wireless.
