Hey Tom,
I have had good success with Shure and Audio Technica. Your right, there are a lot of different manufacturers and models. You will have to determine if you want to go VHF or UHF. Lots to consider when making this type of purchase. You may want to consider a consultant to analyze your sanctuary or auditorium for the right system for you. If your buying from a local dealer, they probably have someone that will provide this service free or at a very reasonable charge.
Regards,
Dennis
