Both excellent cameras which will serve you well. Two considerations to make

1 Which one will sit better in your hands, where are the controls and what are the ergonomics like. Best thing is to go to your local Jessops and try them.

2 Secondly you need to think about the lens system you will be buying into. You will probably spend more on lenses and accessories than the camera so do think about this.

Personally, I wouldn't buy in the US or at the airport. What if things go wrong, you need to return the camera etc, etc. I always buy my cameras at a shop which I can drive to then I can turn up on the doorstep and wring their necks if the camera develops a fault. HTH.
