I think that the "holy grail of the Konica bodies would be the Autoreflex T3n:


All of the "modern" Konica bodies (from the Konica Autoreflex all the way to the last Konica body, the TC-X), offer shutter-priority auto-exposure, as well as fully manual operation.

I once owned a Konica FS-1 body, if you can find one with working electronics, it is an excellent body. But for a bargain body, Konica Autoreflex TC's can be had for a song.
