get the ED coating
From my limited understanding, ED is not a coating, but rather a fluorite lens, which is a lot better than glass and much more expensive. Same with all optics, telescopes and camera lenses too.
With camera lenses, Nikon calls their flourite lenses ED and Canon calls theirs L-glass. Telescope manufacturers call these lenses APO or apochromatic.

If it makes it more expensive, why are they still under $400? Why hasn't this been used in rifle scopes? It has it?

You are right, it is higher quality glass. And there are different varieties:
ED: Extra-low dispersion glass
FL: Fluoride glass
HD: High-definition glass
The ED glass added $80 to the cost of the binos I bought, and it was well worth it.
