What kind of camera does he want? How much experience does he have with cameras? He could probably get a NEX-C3 used for that price, but if he wants something to hunker down and learn on, a normal-size DSLR from one of the major brands would probably be more comfortable to work with. This is just my highly biased opinion, though.
No experience. Just to take pics while on vacations and special events. Could be a point & shoot or DSLR. Think of it as if you were buying a camera for your aunt or father.
