Query: All right.....

How good this book is for you depends on what you want to do with it. If you need basic vocabulary and lots of ready to use phrases for a vacation or speaking with a certain person, then sure--get it, because it has exactly that. But if you want to learn Russian, I don't think this book is worth it. The CD is great, true, but if you pair another book with Pimsleur, then it becomes just another CD. Without the use of the Cryllic alphabet, you really can't progress farther than this book in Russian, so it's really just a waste. The Idiot's Guide is a better purchase, even without the CD, because it gives you a firm foundation to begin studying Russian. Trust me, if you want to learn Russian, then Russian for Dummies is not the way. It's an OK book, but it's made to serve a certain purpose and that purpose is not the one I think most people who pick it up have in mind.
