I have a Canon A80 (4MP point & shoot) a Lexar 1GB Professional CF Card, the Canon WP-DC900 housing, Inon 105AD Wide Angle lens and adapter as well as a home made base tray with a ULCS ball on it. (Photo of setup available upon request) System has never been flooded. Great starter system. $650 plus shipping.
If interested, I have the UK 800R light that can be used as a constant light source for the camera. You'll just need to get the ULCS ball adapter and an any 1" ball arm for it. $150 for that.
The housing also works with the A95 camera.
I accept Paypal.
I have a 100% positive rating on Ebay under Scubastu.
Happy shopping!
