One thing you could look into is if the pro shop offers gift certificates. Another is to talk to the pro shop operator and see what he or she thinks would be a good ball for the type of bowler he is. If you're looking for some less expensive options, something in the Monster line from Brunswick would be good, they might run you $130-$150 or so, and are great pieces of equipment. It would help to know how he bowls, how he throws the ball, and what he uses now, but talk to the pro shop operator.
