Edit: just checked the date, so maybe my response is a bit late.
JayG, those Intova camera's aren't the best in the world, but you can get some good pictures from them. When my girlfriend lost her good camera, she picked up that Intova package with underwater case since she was a starving student and couldn't afford a good camera and case at the time... We've been using it for a year now, and have gotten some good pictures.
One big gripe, though, is battery life. Don't even think about using alkaline batteries, you'll have to buy quality rechargeable NiMH batteries since this camera chews through alkalines like there's no tomorrow.
It won't be the quality of a good Canon camera and dedicated case, but for a cheap camera that includes a case, it's not bad... But I'd still recommend spending a bit more on a Cheap, but quality Canon camera and case if you can.
About 60-70 feet, illuminated with a 10 watt HID...
About 100 feet, internal flash only with no diffuser (so the case's shaddow is in the bottom left)
