- when you pick a dSLR, you are more likely to choose a system instead of a camera and a lense.... other considerations should be given to the flash unit, existing lense if you have, and the lense you might get later ....
- weight is one factor, but it is recommended that you go to the store and play the camera yourself and feel if it fits you. Canon Xti fits well in small hands, while Nikon D80 fits big hands better. do not forget to play the command dial to see if you feel comfortable with them or not....
happy shooting ....
