+1 for Evod and Ego battery - looks good, vapes great and easy to rewick and coil your own heads. My only problem is I think related to my juice, which gunks up coils really quickly. I have to rewick and coil every other day, otherwise it starts to taste grim and I can get some leaking and gurgling through the battery connector. As I say, I think this is due to my juice really, rather than the setup.
