Just read Andrews online catalogue, and the Black Diamond EDs are very clearly listed as EDs, and the only choice seems to be which mount you want to buy. I don't see anything misleading about their ads. When you look at the listed specs for the other refractors, it clearly states they are achromats.
I have dealt with Andrews on several occasions and have found them very good to deal with, as are most of the dealers. And their prices are usually cheapest.
