Don't buy him anything else, simple as that. It wouldn't be right; you got him something that was thoughtful and, presumably, within your price range. I am assuming that he also did the same. It's totally ok if your price ranges are different and you shouldn't feel pressured to have to do more than you already have (although I totally understand that feeling). I am sure he'll love your gift. If he cares about the dollar amount then maybe you should take a good hard look at his values and see if maybe their out of whack with your own in a way that'll be problem.
