Thank you psyc63, any suggestions for a rebuildable atty ?
Sorry to input against another posters recommendations but the laundry list of problems with the 213 should wipe it out of most people's choices. On a personal level if someone can live with its limits (broken TC, No upgradability, only 150w-160w, loves the style and form factor) but realistically its an un-recommendable product. Same formfactor I would suggest the IPV6X until I hear of other issues developing. If outright power isn't need a SMY SDNA75 single battery mod is pretty good. If not dealing with long 510 pint Atty's a RX200S or RX2/3 is a good option. The H-priv is well respected. On the upper end a Triade or HCigar VT133 might be good options to get into some higher power DNA fun.
Atty's become a bit more of a mess. Highpower. Taste. Liquid capacity. Ease of building. These all play a part. A borderline MTL lung inhale I would suggest a SXK or Tobecco Kayfun 5 clone or an Avacado 22m. For Power something Like a Aromamizer supreme (or Boreas (my preferred if you can find it)) great taste but dripper decks and airflow with 7-8ml juice capacity. Juice capacity really goes to those or the Herakles which wins on with like a 6.5 ml tank but easiest wicking. The easiest to build on, good flavor, and decent size juice capacity goes to the Limitless RDTA Plus. Though that needs a bigger build to shine. The regular Limitless is probably a better compromise, but then it shifts itself back to some of the regular tanks (like the Supreme, Boreas, or Herk RTA-2) as being all around better buys. Larger tanks like Modfather, Dump Tank, or BFDFT I would stay away from till you get comfortable with them.
If you are looking for a more regular sized actual tank that will fit any mod. I don't think anyone ever really unseated the Griffen 22mm.
