From what a lot of people have said, the build quality of Razer is not that great. If you are serious about an RTS keyboard, get a mechanical board with Cherry Brown switches.
My vote goes to the Filco Majestouch 2 after using a membrane switch Logitech Wave for close to five years. Yeah its a bit expensive, but you will not be disappointed in the quality, feel and longevity of the Filco.
