EV grade are 1/3 more not 2x. Cheapest grade B right now is docan 600 + shipping (60 from houston warehouse) = 660sure, but do keep in mind this will essentially double the price..
so it's all in the eye of the beholder
Cheapest EV grade is Luyuan 148 + shipping (which is about 170) = 762 (but if buying form alibaba you'll have sales tax and fees for most states so meh about 80 to cover it or so)
So worst case its about 22% more, if your state doesn't have taxes then its only 15% more.
the only thing with luyuan is its a 90 day wait.
