Gaming Keyboards: Need a Recommendation

So I use the Merc keyboards for gaming. (Merc and Merc Stealth). Both were Ideazon products, now they belong to SteelSeries.

My current Merc has started to go on the fritz were the keyboard shuts off. I need a replacement. I'm not sure I want to pay 90 bucks for a third Merc in 3 years. But my big hands have become so accustomed to the way the keys are setup on the left of the keyboard. http://www.steelseries.com/us/products/keyboards/merc_stealth/information My hand starts to cramp after awhile when using standard keyboards. But I suppose I could re-adapt if need be.

What do you guys use?

I used to use a zboard, but now I use a rergular HP board that came with my new computer

I use the G15 old series the black and gray one have had it since they came out and Love it would trad it for anything but that one has potential

I ended up just buying an ergonomic keyboard from Best Buy. I bought it before the BC2 game night last Saturday. Like I had said my kb was broke and I wouldn't have been able to play with it, so I settled for it, Best Buy had a poor selection. Though since we didn't end up actually doing the BC2 thing I haven't really tested. But it "feels" ok. We'll see what happens.

I would have to say that all those high tech keyboards are nice but expensive. I have been playing mmo's and computer games for a very long time now and using the basic board is just as good for me.
