razer deathadder old version (blue or black) not the new 2013 (green) version.
mechanical keyboard. personally i prefer ibm or unicomp for buckling springs but cherry mx blues arent bad if you go with wasd, maxkeyboard, ducky, das or deck.
I absolutely LOVE my blue death adder and blue black widow. In fact, as soon as I get some extra cash I'll be ordering a second set of them for whenever these start falling apart.
