Best Professional SLR Digital Cameras

Im young but i want to start early on my career as a photographer and that means i want a good camera. I already have a digital camera and a 35mm SLR. I want a DSLR but is this the right one for me.

Any info you could provide me with would be awesome! I’m buying my first SLR Camera, and have read that the D60 is a great one for beginners. But i’ve been looking and I can’t really tell the difference between the D60 and the D80 , except for the price range. Which would you recommend?

hi. I am 14 years old about to be 15 and Im looking to upgrade my camera. I really want a Nikon Slr because I am getting more into photography and would like a good camera. I need a camera that will take amazing pictures and will last at least 5 years. I take picture of my friends, nature, animals, and things that I see while on vacation. Which one would you recomend for me? THANKS!
**Also, everyone that I know recommends a Nikon over the other brands so I got my mind set on a Nikon, so I would appreciate it if you told me why one is better than another instead of telling me about a completley diffrent camera. Thanks so Much!
