Keyboard

[Jokers Fury]

I use the BlackWidow Ultimate Mac Edition and I haven't had a single problem with it since the month it came out. I use it with WoW, LoL, GW2, MineCraft, etc etc. Haven't had any issues or complaints from it so far. But if you are looking for the ultimate overkill keyboard go with the Razer Deathstalker.

I am going to have to agree with the many recommendations for steelseries 7G or 6g.
Response time when moving in game is superb. Multiple button presses will register without confusion. I personally feel it is very solid built.
I love to remove the keys and add my own to customize, the caps that come with the 7G fade too fast for me.

Would also recommend das Keyboard http://www.daskeyboard.com/. I would have got das keyboard, if I didn't find the excellent deal I got on the SteelSeries I own.

Edit: also read that daskeyboard has comfort that typists look for.

I would also advise getting the daskeyboard, those things are knarly, a buddy of mine has one and it is extremely addicting just to type on it haha. The clicking sound they make is awesome.
