Easy to collect, I have two, a QL17, and the oft scorned Canonet 28 which despite being an automatic camera, or manual with just apperature selection is fun to use. The lenses arent to shabby either. I used the q-tip and alcohol method to clean my viewfinder, becareful about cleaning the rangefinder assembly!! this page: http://www.kyphoto.com/classics/forum/
