I need a digital SLR for shooting horses in motion and some tropical beach landscape shots. I'm a still kind of a beginner even though I used to own one of the first Canon Rebel XLRs. I did not like it because it felt to plastiky.

Which one would you recommend me?

- I don't use flash.
- I don't own any lenses of either brand.
- I am probably going to go with a 18-200mm lens
