I know you don't see them much but do you know if they collect things? If not gift cards are always a hit at my house. Our guys really like gift cards to the movies, itunes, Old Navy, Mall, etc.. If you are attending you could make a basket of sorts and put the gift card in it. My son recieved a small bucket with his favorite sports team with a GC to the movies, popcorn, a collector's edition bottle of soda and some of his favorite candy. It was nice and yet not overly expensive. He enjoyed the snacks while watching TV at home, went to the movies and still uses the small bucket as a mini trash can. I'm sure you could do something similiar with you brother's favorite things.
