Don't have much to add to what's already been said but I have 3 different e-cig setups now, a container full of spare parts, tanks, atomizers, clearomizers, and tons of juices. It happens to most of us in here! My ProVari is what I use when I'm sitting here at my desk working all day, I have a couple of eGo 650 batteries and Stardusts if I'm going to be out for awhile, and also just bought an eRoll kit for the same reason. Anyway, welcome and enjoy your new hobby!
