WANTED: Christiane F. book - $30 in Montreal, Quebec for sale

Does anyone have a copy of Christiane F? It is an autobiography of a teenage junky in Germany written in the late 70's. It was originally published in German, but the early English editions were printed in England.

I used to have a copy, but unfortunately I lent it out and now it is gone. Sadly, I now realize that most of the subsequent editions were printed in the States.

I do NOT want the 1982 version. There are huge chunks of text that have been edited out and the writing is different from the copy I had. There are little differences, like the copy I had used British English (calling a vacuum a hoover instead of vacuum).

I would love to have a copy like the one I had :)
