[SOLVED] Keyboard with at least 4-key-rollover (german layout)?

[aik]

Hi!

My keyboard doesn't react to spacebar, when I press 2 arrow keys the same time.

Since I don't like using other keys mapped to space - can any1 recommend a keyboard with german layout for playing worms?
It doesn't need to be a gaming keyboard - I don't play other games than worms... so affordable would be the important thing after solving the rollover problem.
