Atlantis has no rba but supposedly they are finally giving in to customer demands and working on it. There are people selling on eBay a supposedly compatible one from a different atty but it reportedly does not allow enough room between tank and RBA body for juice to flow properly. The RBA head for the other atty costs like $7.95 but to make it work you have to drill 2 wicking holes in chamber body. There is a guy drilling the holes and selling finished units for $113.95 on eBay! How many he is selling at that price, I cannot say!
The v2 version works great and I even found tme online in UK for £8. They are not just the segatank RBA drilled out, they are quite different in terms of threading etc also so as they fit the atlantis properly. The $113.95 thing on ebay is strange as he was selling them for $13.95 before,. I think he is using it to placehold that page while he gets another batch maybe?!?!?
