What do you consider to be 'the music video look'? Most of the style and look of a music video has more to do with lighting and directing than anything relating to the choice of camera. I know lots of people who have had great success shooting music videos on those plastic Krasnogorsk-3 cameras. They're loud, but music videos never (almost anyway) use sync sound. But if you're determined to use a digital video camera, I can't imagine a prosumer camera that would work fine for a general shoot. It really boils down to what special needs your shoot has.
