Dan Brockett's article Includes prices, tech specs, photographs, and audio files for listening to samples from each in various situations. In the event you end up shopping for a lavaliere, this article would be a good place to begin. Prices range from $179-$600+ but you can find them used for significantly less if you know what you want. The thing with used mics is, they may or may not have the connector you require, so check it out first. When buying new, the seller will wire whatever connector you wish, usually included in the price. The other thing to be aware of with used lavs is cable length since in the field they are often damaged and repaired at the connector, whereupon the cable is shortened. Make sure there's enough mic cable left to be useful to you. Another factor is that dirt & sweat salts gather in the mic screens, so used lav mics are likely to sound a bit flat when compared to new. You might want to delicately clean the screen on purchase. Someone asked me once if there was a cardioid lav and I said, "No." Most are omni-directional. Apparently there IS a cardioid, and it's specifically designed to be 'seen' and used in very noisy environments. Were I to dedicate myself to doing conference interviews regularly, this is the mic I'd choose. Happy shopping!
