The Steelseries 6G v2 is cheaper than the 7G, without extra USB plugs and the wrist rest, and otherwise just the same. I've been thinking about getting that one since it is great overall with no unnecessary extras. The only thing that they could do better is make them with thicker keycaps. Don't shy away from using a board with black MX switches, they are actually rather nice.
If you're in Germany, why not get a G80-3000? They are only about 45€ and NKRO is not really a must-have even for a gamer. You get the choice between black, blue and clear MX switches. Cherry's keyboards are not as heavy and sturdy as the more expensive ones, but I don't think that means they'll break.
Unfortunately there is no German Layout Version for the 6gv2. I asked Steelseries on Twitter for that, Answer was:

@ As far as I know we don't have plans for a German 6Gv2, sorry
SteelSeries SteelSeries
@ Sure it is - but we didn't really get any interest from that market on this one particular product.
Otherwise i would of course look for a 6gv2.
About the G80-3000, man really, i hate the look of this Keyboard, its so big and ugly.

But you say, black switches are okay? I saw so much People raging about black switches for Gaming, especially for RTS Games. Hmm i never touched a Mechanical Keyboard, so i can not compare.
