You're gonna get more bang for buck with headphones.
I'd probably skip the 212's though (wasn't impressed when I heard them). A few better options are Koss PortaPros2 ($19.99 at CircuitCity at the moment if you order online for instore pickup), Koss KSC35 ($35 from Koss.com), Sennheiser HD497 ($55-60), Grado SR60 ($60-70), Alessandro MS1 ($99 shipped), or Audio-Technica ATHA500 ($99 imported via Audiocubes.com).
As always
Head-Fi is a good place for headphone info.
