I love my 7D but can't really get on with the video part of it. Nothing I film looks amazing... guess a lot of it is in the post-processing ?! Didn't buy it for the video capabilities though...
As mentioned above .. go have a play with both at Jessops or John Lewis or Currys/PC World/Dixons.. I did this with my first one when I was debating 450d or Dsomthing nikon related.. couldn't get to grips with the nikon where as the canon just felt right, everything was easy and obvious, even to a complete DSLR novice !
Jessops web-price matched mine (thank you, smartphone !!) but not sure if they do that any more. The guy told me I'd got [the 7D] for less than his staff discount would have done ... :evil:
