Thank you for your words Pete.
Having used Exam Cram 2 for my Security+ studies, I know it provides you with the foundation required to pass any exam.
I don't believe I expressed myself correctly in my previous post, so here's something to clarify my opinion on EC2.
Prior to studying for my previous exams ( 70-270, 70-290, 70-291 ) I did a little bit of research before I bought my books. I found mixed reviews, and some EC2 books had very good reviews, but it is my belief they will most likely come short on certain topics you would need to master in real life.
EC2 books have been written with the sole purpose of providing the basic foundation of the topics so you can go ahead and pass the exam. For CompTIA, it has been proven EC2 is an excellent book to use for exams, but for Microsoft things could change. Microsoft has a unique way to test your understanding of the material, and they're always trying to trick you in a way or another that's why I believe it is best if you use the books made by them in order to study for the exams.
That's not to say you can't use EC2, or Syngress. In fact, Syngress has written excellent books for the MCSA/MCSE tracks. You can use EC2 for review, and for your last minute cramming, but try to use either Syngress or MS Press as your primary book.
As previously mentioned in my post, EC2 could get you through your 70-270, and even through 70-290 if you got a Windows 2003 Server at home, or a virtual PC with it installed. For 70-291, and 70-293, I wouldn't recommend you to use EC2 other than for review because there's a ton of information to grasp, and a lot of exhibits you should know by heart in order to pass these exams.
I don't know about 70-294 or 70-298, but I have read someone who was able to pass both by using EC2, along with CBTnuggets.
Sorry for my long post, and I hope the information provided will help you, and some other users as well.
