Thanks all - great info - the Canon looks outstanding! This has turned out to be a really informative thread!

Looks like the upgrade will probably be another casio - the exz600. I've been pretty happy with the ones I've used - particularly in low light. I got some amazing shots one night after sunset under dark overcast at about 25 feet of depth when the water was quite cloudy - fish I could barely see - and with no flash. Plus it'll do 640x480 movies and has the 2.7 diag lcd.
Housings haven't quite hit shore yet but are expected anytime.

I originally went with the casio because of the pentax lens and reputed good low-light.
