My main camcorder is a Canon ZR800 MiniDV video camera: The picture quality is pretty good most of the time, but sometimes the built-in mic picks up the sound of the tape mechanism rolling. I don't want to always have to use the noise-reduction features in iMovie '11 or something, and I think Canon was aware of that possibility, because uniquely this camcorder comes with an external microphone jack! I am looking for a good microphone I could purchase for it well under $70. The ZR800 doesn't have an accessory shoe, but I plan to use the microphone either by hand-holding it while the camcorder is on a tripod, or using it on a boom stick. Any mic shaped like these would work: Well, except maybe the one on the far right. Any recommendations?
