Ok, so options continue to grow. I guess at this point maybe considering an FA and a 35mm F/2 and just sticking with that--seeing as though that's my ideal lens and I really prefer the older build in my hands. I just got offered a gorgeous nickel plated Zone Vi 4x5 with two brand new Schneider lenses for a good price, so Nikon stuff might not be top priority at the moment!
If you need the featureset of the FA then there is no manual focus Nikon alternative. Besides, it really is a fine shooter!
