I think the "xtreme duty" and "severe xtreme duty" labels on the ETA box blades are in reference to the way they are designed and built to be very strong, and have nothing to do with their weight. They look like they would stand up to extreme punishment without bending or breaking.
That being said, I have been holding off on buying a box blade for my Kubota M6040, which is a Category II utility tractor (not a compact!!!). I think ETA's current box blades are a good value in terms of cost for the great quality of construction, but I am looking for something a little bit heavier, mainly because my tractor can handle it and I want more weight for ballast, and for cutting in really hard ground. I would be really interested in an 84" blade made of thicker steel and weighing in at about 1200 lbs.
