I just started vaping 3 weeks ago, so here is my advice.
Since you speak of confusion reading stuff here, I'd suggest deciding quickly on a recommended starting kit that fits your budget. I found that once I had a basic vaper in hand (eGoC battery with an EVOD), everything I had trouble understanding here before finally made some sense. And now I know what I might want to improve on. For example, now I see that I really don't need a more powerful battery than the most basic 650mah eGo I have now, but that I might want to get a different tank, like the Aerotank.
I did research here a year ago, but it all got too complicated and I just gave up. So, if you feel that might happen to you, just make a quick decision and once you get the thing, it will all make more sense. (Also, get the right nicotine level.)
