Cherry-G80-3000LSCDE-2-Tastatur-USB-schwarz
this one has blueMX switches, just like the Razer Blackwidow.
see here: clicky / Klick Druckpunkta German layout "gaming" keyboard for a resonable price is the
Steelseries 6gv2 - about 60,-€
This one has 6KRO and black switches. The cherry G80 has 2KRO. I play a lot with both a G80 and a 6KRO keyboard and dont feel any difference.
Also TTeSports Meka G1 seems to be a candidate, but 100€ is a bit much imho.
For 100€ and more there is the DAS Keyboard.
You can also find a lot of second hand keyboards from cherry for nice low prices on ebay like
this and
this.They should be with blackMX. Mostly in good shape. I own a few of these, too.
