I would go for an Ontario, Becker or EESE in that price range. The Schrade SCHF9 (?) is also a winner. Carbon Steel, readily available and reasonable priced. He can choose what he wants and buy it new. You won't feel hurt when he trades it for a game cartridge or movie tickets.

And if you're giving out Busse kin for your kids, let me stop by your house and call you daddy too!
