With the holiday season approaching I am considering asking for a Razer keyboard or mouse. Currently I have a pretty standard keyboard and a wireless "gaming" mouse (http://www.amazon.com/E-3lue-E-Blue-2-4GHz-Wireless-Optical/dp/B00CBLVVZE/ref=sr_1_8?s=electronics&ie=UTF8&qid=1382049196&sr=1-8&keywords=E-3lue+Cobra+wireless). The question is, which one should I pick. I have heard mechanical keyboards are great, but I don't know which Razer keyboard is best, or whether buying a mouse would be a better investment. Also either one could not be over $150. (I play mostly FPS and action games)
