On a semi-related note, the Rode VideoMic absolutely rocks. I bought one for my Sony camcorder, and it seriously pulls in high-quality audio. Plus, it has -10dB and -20dB pads to adjust to different conditions and camcorders.
I tested it on the 120 and it was strong and clean. I could hear all kinds of noise in the house that I wasn't aware of (creaks, hums, air flow... kinda cool, actually).
It is *not* stereo, and although it is *not* meant to be handheld (fits a camera shoe) there are handgrips with shoe mounts you can find at photo camera stores. It does have a shock mount, so handholding it on a hangrip would not make for much handling noise. Rode also makes a windsock (aka "dead cat") for outdoor windy conditions, like those fluffy zeppelin-shaped mics you see on pro audio booms in the movies.
I understand the stereo version does not have the presence or reach that mine has. But I love it. Runs off a 9V battery. Costs about $150. Not small, and not for stealth taping.
