I don’t get the members only idea. Anyway,
My entry for Switzerland would be:
Zurich, Walk in Pro lab: http://www.Studio13.ch, Hafnerstrasse 24. E6 in 35mm and 120. Same day. Reasonable prices for developing. Prints are expensive in Switzerland, so stick with developing only.
Zug, in central Switzerland, (between Zurich and Luzern): http://www.ars-imago.ch. Developing service for E6 and print film. Good selection of film in all sizes, 120, 620 b/w, LF, Polaroid. Also chemicals, paper, etc.
