Would it absolutely have to shoot 1920x1080? Frame rate important to you?
If you're just going on a bit of hearsay, maybe investigate the significantly cheaper other offerings from Canon first - 550D, 60D, 7D or Nikon - D90, D7000 etc. This is assuming you, for some explicit reason, need a DSLR capable of shooting video.

If you don't. Get a dedicated video camera.
