Thanks, yes, I've seen that site, it's a comprehensive one for that camera.
And as far as I can see, for the money, around $1100, that is the best deal
out there.

I'll check out the housing you suggest and the light package also looks like
a good way to go.

The VHS comparison was, I agree, a bad one.

Thanks,
