ECF. I have had good experiences with them - the mods are very strict on how they are run. You need to get verified before you can see or participate in them. Same thing with the classifieds. Do it right away, because it can take some time to get verified. Them you can start buying, sellling, and trading.
Provari V2, 3 eVics, Protanks - works for me!
Relax, don't do it . . . when you wanna VAPE.
