P.W.
one thought is money towards one of the electronics. Or an IOU for a certain amount. You may not like it, but electronics are what boys like! If it is truly important to him he will save up for it.
Footballs or sports items. Favorite DVD's. Buy a used guitar and find a student to offer lessons. CD player, CDs, posters, movie tickets. If an ipod shuffle is too expensive ($55 at target) then start asking around to buy a used one. Lots of people upgrade and then have no use for their old ipods.
