I'm using the Razer Marauder. I've never liked the feel of mechanical keyboards in regards to typing up papers (too loud, weird feel). But to each their own!
Specifically got it for the backlighting, and it's capabilities with SC2, as well as macro configurations. I've had it for 2+ years now, and I have no complaints. Even after a couple of years, the keys are still gorgeous and don't actually show signs of traditional wear. The lighting is customizable, it has a braided cable, and it's a tad bit smaller in length than your traditional full-sized keyboard.
Because they have integrated the arrow keys into the numpad, toggling the numlock can be a pain, but it's my only complaint.
+1 for this keyboard if you can find it!
