I'm looking to purchase a cheap but effective underwater video camera for use in swimming pools as an aid to swim coaches looking to improve the technique of their swimmers. My budget is about $750.

I was looking at this.

I'd like to be able to put the camera in the water and use a cable to feed the video to my camera, a laptop, or VCR for recording/viewing.

Hopefully, I'll finally be able to combine my love for swimming with my love for video. Thanks for your help guys.
