ankawa,
I’m very pleased with the Rode Videomic I’m using with my DVC30. It costs about $150, and performs exceptionally well for that price range. It has a mini-plug, so you don’t need to buy the XLR adapter. Azden and Audio-Technica also make some mics for video camcorders which accept mini-plugs. But if you do get that XLR adapter, you can use the more professional (and much more expensive) XLR mics. Sennheiser is a popular brand of XLR mics, such as the very desirable MKH416 ($1100).
Some of the mics sold in music stores might not be appropriate for video work. You need a condenser mic, not a dynamic mic, in order to get a good strong signal for video work. Also, it should be highly directional, like a supercardiod or shotgun mic. http://www.bhphotovideo.com and http://www.calumetphoto.com are places that sell mics for video.
Good luck,
Ken Hull
