Which keyboard? ZBoard MERC or Cyber Snipa Warboard?

guys, i'll get straight to the point.

the dilemma is this: at the same price, two gaming keyboards:

and

i like the 11 degree tilt on the merc, as well as the butterfly shaped keys, but the Warboard generally looks to be of higher quality... can anyone who owns either or both of these keyboards give me some feedback on them? I've read a few reviews but am still undecided...

then theres these (only slightly! wtf!) cheaper gamepads which further complicate the matter:

http://www.pccasegear.com/index.ph [...] ts_id=5568

you can tell the TT and Cyber snipa copy the ZBoard/fang "butterfly" WASD key design, with the TT looking almost identical button wise. the cyebr snipa is fairly lacking in buttons compared to the others, but again: does anyone have any experience with any of these/advice on which is better?

thanks in advance for any answers and my apologies for a probably poorly written OP
