Rslomkow is right, very attractive price for 7mp photos and 640x480 30fps video.
I think that you can have some sort of basic underwater color correction for videos also by choosing Set->My Colors-> and then Vivid Red.
The housing is the WP-DC 80.
You definately need a 1gb card or greater since it stores video in very large .avi files, appr. 1gb=8~9min video.
An annoying thing is that you cannot use the zoom function during a video. You must choose your zoom level before you press the rec button. So if you are filming a fish in a large distance and it decides that it wants to come a little closer to you

you have to stop the video, zoom back and then start again!
