First up, let me correct some misconceptions in this thread.
Nikon D40x, D40, D60, D3000 DO NOT have focusing motor in their bodies. Neither do ALL canon cameras.
Why does this matter? Simple. ALL canon EF and EF-S lenses have inbuilt focusing motors, and therefore do not need internal focusing motors in the body. But, older Nikon lenses do not have this focusing motor in the lens, and therefore require an motor in the body to autofocus. This is limiting the lens selection to those particular lenses which DO have the motor in it.
Second, to TS: why not wait a while, as Canon and Nikon are probaly going to release new entry-level models in a matter of weeks. I think that it would serve you much better to wait a while and see if any of the new models are okay for you.
Just to let you know, I'm using the Canon 1000D myself, and i find it okay.
