I'll go against the grain and say dive in head first. You can read yourself silly in the forum. You're revved and ready now. That's half the battle. Let's go do it! You have a world of help here backing you up as you have questions.
For less than the cost of a carton of smokes you can have a kit with enough power to keep you vaping for months, some cartomizers to get you started and 18-24mg nic juice. Most people don't get enough satisfaction from a cigarette-sized ecig. You can't go wrong with an Ego, Kgo or Riva. They're all pretty much the same- called 'fat batts'. If something the size of a Sharpie pen is ok with you, this will probably be a good fit. Kgo packs a little more power and the battery lasts longer. It's 39.95 for a kit at hoosierecigsupply and breezesmokes. Egos and Rivas are good also, slightly shorter battery life and a little less voltage. Liberty Flights has them for about the same price.
I like these vendors because you can get everything in one stop
Kit
Cartomizers
juice
It's not rocket science. It just seems like it when you're first getting started and don't know the jargon. Good luck to you.
Well said!!!!
