IGX

I purchased one at Best Buy. I'm very happy with it. It's simple. It gives very quick feedback on technique. I with I had one years ago. You can watch a clip on the player seconds after you take it on the player. No rewinding. A simple connection to the usb port of a computer and you have nearly instant access to the video. It seems to handle low light very well and will take one hour of video. The quality, even when played slow motion, seems very good.

I can't really comment on battery life yet, but it does shut itself off very quickly when you quit recording to save batteries.

The only disadvantage is the lack of a lens cover, that would be nice.

I'd highly recommend it. I expect it to help my workouts. I've already spotted a flaw or two in stuff I do.
