Ok so I'm looking for a shotgun mic for like $100 or less. I'm not a pro at all when it comes to recording, but I know you can do a lot of DIY stuff and improvise to make fairly decent videos. Most of the shooting is for fun and for my job like doing skits and things like that though. I work with the youth-mostly college age students. Currently I have a few things, but i'm in the process of buying some accessories and I wanted to add a shotgun/boom mic to it. My camera is a canon optura 20 and probably a sony hc30 or hc40 as a backup. (I say backup b/c I just like canon cams better.) We used both in college and I've liked consumer canons better. Anyway, $100 is my max, but ideal would be $0-$50. What's the best brand to get, and who usually has good prices?...well, other than ebay. Thanks!
