http://www.razerzone.com/gaming-keyboards/razer-lycosa-keyboardI use the Razer Lycosa. I've had no issues with it, and it's got a really nice feel and response when you push buttons.
The reason I didn't get a G15, is because i'm never going to use 95% of the bells and whistles that you pay for, so I'd rather spend the money on something that A.) feels good and B.) looks good.
It's the same reason I have a G9 for a mouse and not the Razer Naga or the WoW mouse. Too many buttons, I'd just end up binding HL to all of them so what's the point.
