In reply to ianto9:
The one you can buy in La Palud is the worst guidebook I've ever come across, not to mention the most expensive (though I was lucky, my partner bought the guide!). Admittedly I only ended up climbing for a couple of days until weathered off but it has mediocre topos, no route descriptions, at least 1 impenetrable approach diagram and some dodgy grading.
I ended up making more use of my 1980s cicerone guide! (I even saw a copy in the Cicerone bargain bucket at the outdoor show last month)
