Depends really on what your kid will be doing, and what kind of TV he will be using?

If he doesn't have an HDTV, and won't be downloading alot of stuff and playing online etc go for the core.

If he has an HDTV, and will be playing online downloading stuff, get the premium.

The Elite is really a waste of money unless you plan to use the Xbox 360 for upconverting dvds to HD over HDMI. THe premium has component cables capable of HD games just like the Elite.

I would go for the premium myself.
