Pick up a FightStick and Street Fighter 4 for $29
Even if you already have an arcade stick, don't you need one for a second player? Or to experiment with modding? As for that Street Fighter IV, you probably already have it (or even Super SFIV) if you're shopping for arcade sticks, but who cares? Trade it in or give it away. The FightStick itself usually sells for much more than that — even at Walmart.
