There are so many to choose from, it's a bit overwhelming. I've been vaping 5 months and have 19 complete set-ups. I've tried many & maybe I can save you some time & $$$. The dual coil Kangers, V2 & Mega, are my favorites. I don't have a good "fiddle factor", tolerence & these work very well with very few issues. My favorite battery is the MVP 2.0 with the Istick coming in a close second. Both last all day if you chain vape them & are VV/VW, have built in Ohm meters, pass thru vape & are rock dependable. When chosing a tank be certain that it has variable air flow and that your battery has variable volts/watts so you can get the most out of your juice. I would recomend that you go to your local B&M for juice, at least at first, so you can "try before you buy". Also, don't buy large quantities of juice because your taste is going to change. 15 ml bottles or smaller. Later on you can order your juice in larger sizes & save a few $$$ or make your own & save even more. JMHO Hope this helps a little.
