Couldn't find ergonomic nor proper gaming keyboard at all. Was looking for Microsoft ergonomic keyboard specifically but found only Logitech multimedia keyboard at best and decided to postpone buying a new keyboard. The current one is still good and would really only buy the one I want. Either a proper gaming keyboard or an ergonomic keyboard.
But I got home with Logitech MX518 mouse.
So far it feels great. A little heavy but great. I'm going to use it to full with games I play: ArmA 2, Word of tanks and Steel Beasts Pro PE.
