Mad Catz Cyborg R.A.T.9 : R.A.T.9
You can change this mouse to fit your hand in various ways, change how heavy or light it is and how high or low it sits, change the speed it moves at in game, and assign a couple of buttons on it to keys of your choice.
KOR fx Immerz : Immerz
Basically the Immerz is like a woofer that you are wearing, which pumps sound vibrations into your ribcage, letting you feel the direction which sounds are coming from, so in FPS games if you are being shot at you can feel the direction its coming from. Future versions are supposed to make the user feel like they are experiencing rain, wind, weight shift, and G-forces. It won't affect SCII gameplay, but it just sounds pretty sick ^^.
