I'm doing some home video recording (think youtube quality stuff) and looking for microphones to record individual people talking, something like lapel mics. We're doing a cooking show and want people to be able to move around but also be heard whenever they speak. On the cheaper end of the spectrum, what would you suggest? Maybe not the right place for this, but is the audio in this case something I'd want to implement with the camera or record externally? Thanks for the help.
