I used to recommend greenhouse1 for their bridelgess but been having a bit of trouble with quality control and
not getting any response from them is disconcerting.
I recently ordered from
https://www.ikenvape.com/store/index.php. I have a couple i06's and a couple of their new 510s on the way. Another one to consider is
the dripping atty from smartvapes. These are reviewed well and don't break the bank like some of the other custom made attys now out. However, I have not gotten mine yet and can't say for sure how they are.
I have been trending towards 510 for dripping because I have a vapemate and love it. However, I prefer the 306 for dripping overall. Just got a 306DCA which I am hoping can get me back to the 306 and still use my vapemate.
