I'm looking to buy a shotgun mic for my DVX100. I've never had a shotgun mic before so I have been researching like crazy. I'm looking for one that is about $200, xlr, shorter (for use on a camera shockmount), also I want to be able to use it on a boom pole. The audio technica at-875 appealed to me, and my teacher said that the azdens are nice. Please help me out. Thanks!
