I am new to DSLRs and I am trying to weigh all of the options of all of the models. I am narrowing my choices a good bit. I think that I am down to the Canon 30d and the Nikon D80. Honestly, why should I buy one over the other? If you have a different model to suggest, I will happily look at it. I am at an impass and really need your help. Thanks. Oh yeah, the types of photography I plan on doing are: Sports, Nature/Wildlife, Events, and Portraits. Any advice you guys can give me will be greatly appreciated. Thanks again.
