I just bought a "new" 60-year-old Rolleiflex after not having one for 40 years. (I had a Yashicamat in between.) It is a fabulous camera but I have several rangefinders which are better for some kinds of work. I got rid of my Leica M2r in the 1970s, and regret it. I suggest you keep the Leica as it is a fabulous camera. You might decide one day you now have the perfect photo situation for a rangefinder.
