Amazing. Today I am also going to get one so whole day I am searching over the net for best solution.
Anyway, this is the best cam ever, but expensive:
Canon EOS 5D Mark II [take a look @ Youtube for HQ video examples] BUT for cheaper I would go this way:
Sony HDR-CX115eb
or
Panasonic hdc-sd60

Seems like it has crystal clear image, excellent slow-motion [check out Youtube]...
