If anybody love to do underwater diving with HD Camera, I have a new cheaper solution as follows:

Go to MongKok Computer Centre to buy Sanyo Xacti VPC HD1010 at HK$4130
Buy a Toshiba Class 4 8GB SD Card at HK$260
Buy extra battery at HK$250
Buy a Epoque underwater housing EHS1000 at HK$2580
Get a HID light from HK$1500- HK$2380

Then you can do your Underwater diving video shooting at not more than HK$10,000

Look at my attachment and you will like this Epoque housingPM

Thiis very interesting, thanks for sharing

Why don't you directly buy Xacti CA-8, it is designed for 1.5M water resist
