I was planning to buy a new mechanical keyboard and i was thinking of the Razer Blackwidow. Base on my research, i don't know but there are so many versions of this keyboard like Razer Blackwidow Ultimate 2013, Razer Blackwidow Ultimate 2013 Elite, Razer Blackwidow Ultimate Stealth 2014, Razer Blackwidow Ultimate 2014. then i checked the Razer site and only says razer blackwidow ultimate and the chroma thing. i didn't want the chroma. first i just wanna ask what are the difference between all this kind of versions of blackwidow and what is the best version that i can buy from what i have mentioned? i'm just scared that i might buy the worst version of the blackwidow.
