MSR markets several items that are described as "hard anodized." I do not know if they are HA-3 or not, but the elderly set I have is very useful, just as you say, light, easy cleaning, and really hot. I am pretty sure other manufacturers offer similar products as well.
My outdoor cookery includes items that are stainless steel, aluminum, and titanium. They all have their uses, and in particular situations are ideal.
