They’re on sale for the next couple of days for $20 each on the 360, PS3, and Wii, and $10 for the PS2. Shipping is $6, so you’re looking at $26 shipped if you’re interested. Great deal if you’re on the fence, but unfortunately I can’t go back to Guitar Hero after being spoiled with Rock Band. I tried!
