Just throwing this out there for your consideration......
As a new vaper, I would suggest something along the lines of an Atlantis or Kanger sub mini, something along those lines to start. Use that to get you started and finding a good juice you really like, better yet, 2 or 3. Then when you find you want a quicker and easier way to change up a couple great flavors and want something more in a tank, get another like a Big Baby Beast, TFV4, along those lines. But with those, your battery life is going to decrease considerably. So also consider some extra 18650 batteries (please check out the battery section for what batteries are good and where to/not to buy them....very important!) and an external charger to keep things running.
