Not an M3 for me, (a) because I like 35mm and (b) I don't like the weird round corners on the 50mm frame on the M3. Nor an M5 because I just don't like it, though i now there are many M5 addicts. On price, M2. On features, MP. Otherwise, whatever comes up at the right price, in good working order.

You might find useful, though it also mentions digital (you can always hold your nose and close one eye).
