I was wondering if the Exam Cram books are enough since they claim to cut straight to the point. The two certs I am needing books for are network+ and security+ in that order. I was at BAM today and reading through the exam cram and also the the hardback sybex(?) books. Also have any of you used these sybex books. Those hardback sybex books are quite a bit more $ but claim to come with a lot of extra materials on cd. In the end I will probably be buying these books used online at amazon. Thanks
