Firstly, beware reviews praising older editions. This book is the Jan 2009 edition. The others are all for an edition published 10 years ago [before the Eurozone!]. They are totally irrelevant and since I complained to Amazon about this, I see they have deleted them from reviews of this edition..
I have the earlier edition. It should have gone out in the paper recycling box years ago. Legislators continue to legislate, Eurobureacrats contine to hand down directives on every jot and tittle of our lives, local government comes up with new stunts to suit the mood of the incumbent town-hall mafia.
Having said that, I found Hampshire's previous book to be useful. If this book is as comprehensive and well researched it will have nuggets of info that are valid and valuable, even though one must remember that he will have sent in the manuscript around mid-'08. Important things will have changed. For example, last year the public health rules that apply to ex-pats, particularly the retired, changed radically. Whatever Hampshire says in his book about the public health set-up, is now useless.
The main thing to remember is that books like this cannot tell you everything. There will be whole chapters that are useful - at very least interesting - and there may be one sentence that is gold-plated, saving you pots of money and/or very difficult times.
Useful and worth the price as this book will certainly be, it should be regarded as a primer for those contemplating a move. The real gold is to be had on ex-pat forums, where real life is constantly discussed, in real time, by those living it.
