There isn't much difference between the 15th edition and the 14th. Both are very well edited and contain only a few negligible errors. The 15th edition contains an additional chapter on the Analytical Writing instead of the old Analytical section which is no longer used.
As far as I know, the CD-ROM is not very helpful, so you'd better buy the regular edition (without CD-ROM).
I really felt that I got full value for my money, and that's the most important thing. You get a really good prep book, and it is just up to you to use it well.

**Warning**
Don't buy this book if you are looking to expand your reading vocabulary. Reading definitions won't help you expand your vocabulary-it's a very inactive form of understanding. Try "Word Power Made Easy" by Normal Lewis or read the classics which are laden with great words. (If the classics aren't your thing, try Asimov's Foundation Series, it's a fun read and chalk full of great vocabulary words.) If you love looking up definitions or looking for an easier way to expand your vocabulary; think about buying Merriam-Webster's speaking dictionary (mws-1840.)

The only drawback is that the full-length tests are not indicative of the actual CAT test questions and expected scores.
Overall a book necessary to go through before you are gruelled by ETS!
To top it all off, there are five full-length practice tests at the back of the book, in addition to the CD-ROM exam, which can be taken a number of times, and offers (mostly) different questions each time. The CD-ROM exam thoroughly prepared me for the rigors of the actual test.
Yes, there are a few typos in this book, as in almost any other book of this nature, and no, they are not significant enough to greatly alter your prep experience.
I was satisfied with my test results (V 610, Q 650, A 800), and I relied solely on this book for preparation.
I can't contradict any other review, but I didn't find a single error in the math section---maybe because my book was the fourth printing and the typos from the first printing were already corrected. In any event, what was even more helpful than the math review were the math tactics, which enabled me to answer correctly several questions for which I was clueless at to the correct mathematical solution. That was amazing.
I also found the vocabulary section good, but I spent less time on that, since that wasn't my problem area.
Good luck to anyone taking the test. I honestly think this book will help you.
