Hi turretin. From what I see, the Tankomizer looks like a simple rebranding of the ego-T system. Before making the jump, you may want to investigate the ego-T on the forums to find opinions. Some people like the system, but a lot don't. The ego-T system is plagued with wicking problems, leaking problems, and the atomizers are probably some of the more expensive. I liked it at first, but it very quickly outlived its usefulness, and turned into more of a hassle.
If you want to try a
tank type setup, hop on over to GotVapes and check out what can be done. They have the Vision clearomizers, which work very well, as well as other types of accessories to make them look good on an ego type battery.
