Well I just finished the CEH exam a few hours ago. The materials I used are here:

I was kind of annoyed about the test. Some of the questions where the same minus a slight rewording and for example if the answer was "5" then the next time the answer was "five." I also had one question that had the wrong image associated with it. There were other smaller things but when I was done I was much more relieved about being done with the exam, then happy that I passed.
Overall I have to say the material it goes over is good, but the exam is somewhat lacking for what I had hoped to see.
