I am helping my dad choose some basic wireless gear for his church. He has received a proposal for a Shure ULX-based system. I have more experience with the Sennheiser 100 G3 series which has always performed quite well for me and have some features I really like (frequency sync, metal housings, easily selectable output and gain settings, etc.). Any thoughts on overall comparative quality, durability, etc? They are on a limited budget (not a mega-church), so please don't tell me they need the more expensive systems. Second, any recommendations for companies in Western Massachusetts for them to work with getting quotes and help with installation? I'm in Seattle so I can only really do the research for them. Thanks!
