I don't think anyone posted this yet, so look here first:

I did a lot of research on this topic and my shortlist was:

Olympus SP (great by all accounts, good lens, spot meter)
Canon Canonet Giii17 (good by all accounts, good lens, good handling, compact)
Konica Auto S3 (didn't like shutter priority, great lens, slick)
Konica Auto S2 (bigger, great lens, see my post above)

As someone suggested, in the $400 range you may be happier with something more modern, like a Contax G. But I find that a fully manual camera with a good built in meter feels so good in operation and yields so much control in your photography that it's the way to go.

Best of luck,
