I shot this with the Drift HD, it has a remote mic, has lcd screen so you can see where you are pointing your camera at, also has a wireless watch switch for turning it on and off.
The video quality is very good in my opinion and by far better audio than the Go Pro and Go Pro 2. It is a little bigger than theres though. Has a standard camera mount so lots of attatchements.
If the video is a little shaky, I live in Oklahoma and the roads are about as poor as they get, after the video, i got my front wheel checked and it was out of true, 6 months later, had to get the other redone as well.
Word of caution, when you record, the HD settings seem nice but are very very large files, I have a 4 year old Mac pro and recorded at the second highest quality and regret it. record on the lower quality and you will never notice.
A friend gave me the new sony one, and what few videos I have seen of his looks very very good. The colors and resolution are outstanding. I will compare them in the near future.
Here is the link I don't know how to embed the video
