How much is he willing to pay? And when does he want one? I have an iBook which I love dearly, but could possibly be convinced to part with it for the right amount of $, and if it coincided with a good time for me (ideally, after the summer).

I am not sure, I think his budget is around 6-8USD. I am not really sure about the specs and whatnot. I am just doing a favor. I think he may want one sooner than end of summer. But if anyone knows of anyone selling, let me know. Thanks,JC.

Oops I obviously meant $600 to $800 USD.

If he is ready to go up to 800$ then he should definitely add a couple of 100$ and get a new MacBook 13-inch with killer spec.
That would probably last him for a few years
