Depending on your budget, all 3 (20d,30d,40d) shoot at least 5fps. In the rebel series they shoot 3.5 fps or lower so it would make the sequences not as effective. Again you want to save a good portion of you budget. A lot of kids seem to forget this and their images suffer. All of the cameras mentions are beginner friendly although ones like the 40d will need a bit more patience.
