I use a RODE StereoVideoMic with my 7D for video. It works well, the quality is a LOT better then the build in mic (as expected). As mentioned in the other post, it is better for general sound, but not fantastic for dialog. Consider the small Sennheiser ME66 for dialog, but it is very expensive (I believe around the 600$ mark).
Problems that I have: the left and right channel are "swapped". It is a mind teaser, but it depends if you stand in front or behind the microphone to determine which side is left or right. Anyway, when you video a passing car, the sound is going left-right, when the car is moving right-left, very annoying. I solve this by mounting the microphone upside down.
Furthermore, the AUTOMATIC audio input level adjustment of the 7D is VERY annoying.
Hope this helps?
