I buy Innokin 30S and 30B tanks,Innokin mods and replacement coils on e-bay all the time.Never got a fake or dead coil.Serial #'s always checked out as genuine on Innokis site.Prices can't be beat.As far as shipping to England,I don't know.Would be glad to give you several good e-Bay sellers.I personally like the $$$ savings.Good luck.
