I found the easiest way into Nietzsche is the Geneology Of Morals - the Gay Science and Thus Spake Zarathustra are a bit flamboyant if you're looking to get a handle on his ideas. For existentialists he's existential, for post-modernists he's post-modern and for lacanians he embraces subjectivisation - a pretty amazing thinker and well worth the time.
