I finally scheduled and took the Security+ exam today. First off, let me say that I had a pretty good Microsoft security background, having gotten my MCSE in February, and I had passed the 70-298 and 70-299 exams in February.
I used Darril's book along with the Exam Cram Security+ questions book and Selftest and Preplogic tests. Darril's book and the Exam Cram book were great, and the Selftest questions were very helpful. Prelogic was okay, but not that great.
As for the test, I was able to complete it in around 35 minutes. Only a couple of questions were something I had not seen, and overall I thought it was very easy. I got 870 out of 900, which makes me think I missed 3 or 4 questions?
I'd highly recommend Darril's book and the Selftest questions. There were a number of questions that were very similar to the Selftest questions. The only strange thing is I think I had ZERO port questions. I'm glad I learned all those...

If you can take this after taking the MCSE tests you'll be much better prepared.
Good luck to everyone preparing for this test. It was not as bad as I had feared... Just learn the material and you should pass with ease.
Now it's time for Server 2008 and those tests.
