i am interested in these atomizers, where do i buy them? what is the cost (are they cheaper in the long run), how difficult are they to rebuild? what kind of throat hit do you get with them? can they be used on a tank setup? are they the king of rebuildable atty's, and can they work on my provari. basically i want the scoop on rebuildable atty's. i am using a smoktech tank right now with a 3 ohm cartomizer, i just wonder if there is something better out there. this setup i have is decent but im always looking for something different.
