Triple B, forget my prior suggestion, now I suggest buying the drums new, from a store that has a 30 day return policy. That way, if it doesn't work out, you're safe. Just keep it in good shape. I guess I would recommend a Sonor Safari bop kit (it's small sized, will fit your son) Nice kit, good price, highly recommended here. The breakbeat set is the only other one I'd recommend. But yea, 30 day return policy and you should be good to go.
