http://www.ebay.at/itm/-/162080906840?I'll paste the description from the auction here:
ISO-DE QWERTZ layout
Cherry MX Brown switches, except for the spacebar which is MX Tactile Grey
Cherry Stabilizers
PBT Keycaps, laser printed
Integrated Trackball
Double PS/2 connector for keyboard and trackball (see picture)
The board has been cleaned by me (although it was already in very good condition when i got it) and all keys and the trackball work perfectly.
The switches seem to have lost some of their tactility though, which is something i noticed after comparing it to a new board with the same switches.
Shipping to the US is also possible, but it's kind of expensive @19.10€.
Will gladly answer any questions about this board and can also post additional pictures.
