As I am about to embark on a month long European driving experience covering Holland; Germany; France and Spain I decided to purchase a Phrasebook for each. To me, it made sense to buy all of them written by the same author if possible. The reason being was that once you have mastered one, i.e. the information that each section contains, then you have mastered them all.
I found the BBC series very easy to read, use, full of useful information and very helpful pronounciation tips and just the right size to slip in either your pocket or 'bum-bag'.
