Yeah, I still can't find any reference to the charger issues so I'm not going to worry too much for the moment. 95% of the time I'm using it with the supplied EVSE, anyway.
Definitely agree about finding the newest one possible.
In the end, I ordered the -3NA3A unit from Ebay for a total of $990 shipped. It's going to take a week or 2 to get here and then I'll put it in and see what's what.
Interesting that your other old EV gear was complicated, as well. I guess it's maybe because the cost pressure really hadn't cranked up yet, given they were relatively specialist parts on relatively low volume vehicles.
