Alternative that I haven't seen anyone recommend - the Yashica Electro is an excellent option. Aperture priority, 45mm 1.7 lens that is really very good, and a clear viewfinder with a great rangefinder patch. 0.7m close focus so you can get nice, frame-filling portraits. Downside is that it's *only* aperture priority, but that's not much of a downside. Runs on a single battery that's not too hard to find, and one will last you ages (I used mine for 18 months without ever changing the batter).
Can be had cheaply if you keep an eye out.
