This has been discussed on the forum many times. IMHO the key to getting decent shots underwater is to have a camera that is easy to shoot in manual, and to have at least one strobe. This is so that you can select a fast shutter speed to eliminate ambient light and light your subject with a strobe. I had a SeaLife as my first underwater camera and would not recommend it. Go Pros may be nice toys above water but you can't attach a strobe to them. (If you try to shoot in automatic mode, your camera will meter for ambient light and choose a slow shutter and wide open aperture and you will get no-where fast).
