i am fixing to start rebuilding my protank coils, i have minis now but would like to get a nicer rebuildable. i dont want to get into sub ohms and i dont want to spend 100 plus on a kayfun or z atty. do yall have any suggestions? i saw an aga t-2. what is the story with that one? i am wanting to get a higher capacity and 510 connection. thanks.
