Between Canon, Konica, Yashica and Olympus there are definite ergonomic differences; handle a few of them and see what you like. Canon QL 19's are quite a bit less costly than 17's, and almost as good. Also check out the Olympus 35RD and RC series. Even though most you find cheap will need CLA to fix the sticky leaf shutters, they are wonderful picture takers and very quiet. The RD has a 40/1.7 lens that is sharp and fast. There are some nice Petri rangefinders available too, but they were built to a price and may not be worth fixing.
