Welcome... that is the eternal question that has tons of answers and I am sure tons will chime in with good ideas. I would suggest sticking with a variable voltage or variable wattage mod and a great one is the MVP 2. It is on sale for around $40.00 if you look. It will give you the same connection you are used to and offers a really long battery life as well as VV nd VW. I would get a Pro Tank 2 to go with it. You can ultimately learn to re build the coils in the pro tank if you want to. Once you go there the sky is the limit.
+1 too...I just got my MVP 2 monday, and clouds are so huge...almost not wanting to use it at my desk....I blow vape into my shirt so I won't cloud up the office....anyway, I haven't used the I clear yet, been using my Kangers with it....but I'm getting some new juices soon and save the iClear for that
I've also joined the MVP cult.
