I see there has been a lot written about spec'ing and shopping for new wireless systems, but I'm going to request yet another opinion on buying a wireless set up. I'm with a semi-pro community theater company, and we applying for (and will probably get) a grant of $10,000 for 5-7 wireless systems. I have to get quote from at least three suppliers (Canadian, 'cause were based in Canada). I've got one quote already for 5 Shure SLX 14s with WCE6T (Countryman/Shure) mics, antenna systems, rack case, etc. ($6200). I'm wondering about sound quality and durability issues with the SLX system compared to say Sennheiser, AT, or EV. I don't see much here about the SLX system. The outfit we currently rent from supplies an Electrovoice RE2 system (RE97Tx and BPU-2 packs). It seems decent, but we always have trouble with the mics and the cables. They are rentals, so that explains a lot. So can anyone recommend a fairly robust system for $800-$900 for mic/body pack/receiver? The only thing I'm more or less adamant on is the Countryman E6 mic. Additionally, since we'll still be renting from the same provider, will a different system conflict with the EV system the rental guy supplies? I'm not up on all the technical jargon and frequency issues, so I'm not in a position to weigh the merits of one particular system over another on that level. I just want something that's reliable and will deliver very good quality vocals. I'm also curious about batteries. The EV RE2 system uses 9-volt batteries, which aren't cheap, and we wind up tossing tons of batteries after every run. The SLX system uses two AA rechargables, which appeals to me on an environmental level. Am I giving anything up going from a 9-volt system to a 3-volt system?
