Or take this one

It costs 50% of the ENG-GER / GER-ENG one mentioned above by katzenstreik.
Then you'll have to strip the DRM off it (what will take you a long time, have enough patience, 50 Minutes or more is nothing.)
After it will be DRM free copy it to your kindle change your dictionary in the settings - done! Enjoy!
