The big thing with DSLR is to decide whether you want a Canon system or a Nikon system (or indeed anything else). Have a think about what lenses and accessories you are likely to want in the future as well as the camera you want to buy now.
How come you don't consider the T4i if you need shoot films? The T4i may be a better choice as it is Canon’s only model that offers the capacity for autofocus even while in video mode.
