i started off with the Kgo kit from hoosier e cig supply and now i have 2 kgo VV's and love them. do your self a favor and ditch the atomizer and cartridge method and go for some cartomizers. the setup i found works best for me is a dual coil tank but buy the single coil smoktek 1.7 ohm pre punched tank cartomizers for it... huge clouds and lots of flavor. i think you will be pleased with that. also i recommend NOT using the dual coil cartos for this particular e cig because they absolutely kill your battery life, and personally i dont think you get as much vapor or flavor out of them. 1.7 ohm single coils are awesome on this ecig.
