The prices may have changed a little since I bought mine. The Lightfoot guides are more similar to Brierly than the Cicerone guides but are not the same. The include maps and more details than the Cicerone guides. The Cicerone guides fit in a trouser pocket and are more tightly edited buy with fewer pictures.
Hi! If you have to watch the weight you carry (and have a smart phone or tablet), you can also order the guides as e-books. It isn't as satisfying as having the 'proper' book (imo) but it does save on weight.
