Hello, I have been using a V2 Cig since 6/14/13. I don't know a lot about e cigs so I was hoping someone with more knowledge could answer a question for me. I am tired of the expense of constantly buying new cartridges and liquimax blanks which is what other websites call tanks I believe. What is the best e cig to purchase that has a rebuildable tank? They have wicks and a coil I believe? From what I have hard it is cheaper to rebuld than to buy new ones. As you can tell by my questions I really am clueless. Any info would be greatly appreciated. Thanks, Jaxson
