Help me make a wise camera choice before I break the budget

You may want to check out the photography board here since there are a lot of questions on it about which DSLR to choose and lenses for sports photography. As someone already posted, you will need a faster lens than the ones you have chosen. You may also want to compare how many frames per second that the camera is capable of shooting. I shoot tumbling which is low light and high speed. I like that my Sony is so fast. Don't rule out any of the big name camera makers until you read about and handle each one. I went to the store thinking I would get a Canon or Nikon but I bought a Sony for several reasons. I love the live view option to shoot over a crowd. I like that the stabilization is in the camera and not the lens so I don't have to pay more for VR lenses like on other brands.
