Zojirishi is definitely microcomputer, or Fuzzy Logic, as you'll see on their cookers (I think that they are the ones that started that term, but I wouldn't swear to it). If you haven't looked at them in the "catalogs", the prices may shock you. They have all sorts of cooking modes, but if you aren't cooking all those things, you might just want a simple model.
Something that I remembered while you were talking about looking for brands without NS inserts - back in the early 90s, a friend had gotten married, and early on, I noticed that they had a VERY OLD rice cooker (his wife is half Japanese, so cooked rice frequently), with an insert that was not NS, and the rice stuck in it every time, needing soaked, to clean out. The insert was scratched terribly, through the years, which is probably what made it stick so badly. Knowing this, I make sure that I treat my IP as if it has NS, even though it is SS, and use only wood, plastic, silicone, and other implements I use in NS. Highly polished SS is somewhat non-stick, but it scratches up quickly, with metal implements.
Rice only sticks a little in that SS insert when left for a long time, after finished cooking, which I rarely do. Like other cookers, it goes into a "keep warm mode", which I'm sure that your old rice cooker has.
