In reply to ruckman:
the german (original ) edition IM EXTREMEN FELS is quite rare and the first as well as second edition
( 2 or 3 routes were changed) are sold from 100 up to 250 € . You can usually find 1-2 copies for sale on amazon. although the selection of routes isn't very 'extreme ' by todays standard ( well, some are very extreme ...), most routes are great classics worth doing and the photos by Jürgen Winkler are superb. IMO worth buying.
