Prosumer Camera to Buy

I am thinking of getting a pretty expensive camera, like $3000 to $6000 range.

Maybe Canon XH A1, Panasonic HVX or Sony PMW EX1

But EX1 has the best resolution but a different kind of chip called rolling shutter...

Anybody have experience with these cameras or recommendations? Want to make short films, shoot weddings, music videos...
