I'm in need of a wireless microphone system to capture the vows and speeches at a wedding I've been asked to capture. What brands do you guys recommend, brands to stay away from? I've noticed looking through B&Hs website of wireless labels and combos that several models are the same price but have different ranges of frequencies, what frequency range should I look for? I'm not necessarily stuck to a budget, but would want the most bang for my money. Does anyone know of shops in Phoenix Arizona that rent such equipment? Thanks for the advice in advance.
