Hello Istorian. Good decision.
Now, what U need?
......because if I go even two weeks without smoking it will have paid for itself.....
This indicates that you're an "eGo class" smoker (nu pun

). There's a rant that all advise is: "Get an eGo" (or Inferno/Riva/Tornado - theyre interchangeable, batterywise, and the battery duration's the "key" here).
I've just broken in a Tornado Tank atty+carts this weekend. It works splendidly. To a T-set, you can at the same shipment order a "standard" (510-)atomizer and a (510-)drip tip. Then you have that option, too. And remember to get JUICE in different flavours and strengths. Up to 18-20mg you could go, and down to 8-10mg. But
at least 30ml in first shipment. And a syring with a thick needle to fill tanks (buy five extra empty carts - no big deal). Then you can fill for a couple of days worth.
So - the investment may have to be for three weeks of smoking - but then you're flying right off !
You'll say 'Tank You', eventually

Oh - heard that one before ?
Good luck to you.
