This may sound really dumb, but I want to make sure

  Hey guys, this is my first post here. So, after watching TS for a while, I've decided to build a PC (in the future). One of the first games I will purchase is Starcraft 2. I never got the chance to play it becuase at the time, my computer blew.

  So, I did some research and found out something. People can get banned from using certain keyboards/mice? I had no idea. What I am really here for is, what are some keyboards and mice are, I guess "legal" to use?

   Thanks guys.

Last time I checked, there were no official postings about periferals getting you banned from games unless they have an auto play macro. Most of the time you hear that kind of stuff it's just some really bad QQing players who cry a lot about their losses. Just go with what you think would be most comfortable to use and buy that.

As far as I know, isn't being banned for certain keyboards/mice only for organized tournaments, where they have to make sure people aren't cheating against tournament rules?

I'd say pretty much any keyboard/mouse from Microsoft, Razer, Logitech, Cooler Master, Corsair, Steelseries, Thermaltake/Tt eSPORTS, and any other major brand would be fine.

Well in that case, do you recommend anything? I'm thinking of the SteelSeries Kana.

Yeah, its only in tournaments, that's why you are required to use the provided equipment.
