vdubmixer:scubaBob, do you like the HD10U? I was thinking of getting one as a second setup with the ikelite housing.
I do like the HD10U. I really haven't had a chance to do much shooting with it, but I did take it to Bonaire last year (right when Ivan was passing through). I've been really impressed with the results. The chroma-noise is a little annoying - but I've been able to remove most of that during post. Color reproduction seems pretty good - but I haven't seen comparable footage shot with the FX1/Z1. I've attached a yousendit link to some sample footage (WMV 9) , let me know if you have additional questions...
