Flukx, Pampered Chef has representatives in Germany and I can put in a referral for you if you really want a stone ... I am not self-promoting and to my knowledge there is no personal benefit for me to do so, I promise. But I do love my stoneware and think every kitchen would benefit from at least one good piece. Send me a PM if you would like me to help you, otherwise just go to The Pampered Chef, Ltd.
and maybe you can search for someone local that way (we can on the US and CN sides, but not sure about European as that is a different business segment altogether.
