CCNP All-In-One Desk Reference For Dummies

[gravatier]

I consider to buy a copy of "CCNP All-In-One Desk Reference For Dummies". I didn't see it
in a book store in my hometown so far however at a couple of internet bookshops. What they said is this book would match in most respects on CCNP. Is it a good recommendation or should I invest more money in cisco-press titles to be well prepared for CCNP?

Many thanks in advance..
