If I were to be starting again.
I would go straight for a mod that takes 18650 batteries, like the Provari, Vamo, Lavatube etc.
I would get at least four 18650 batteries and a charger.
I would get a selection of Clearomisers (and spare atomizer heads) like the Vison, Evod or Kanger T3
I would get a selection of Dual Coil Tanks (and spare cartomisers).
I would get four large (50ml) bottles of Dekang Apple/Juicy Peach/Mango/Blackberry/Blueberry 18mg liquid
All this would cost a fair bit, but I would be set up for a long time and would be spending no more for a long time.
But first you must know if you are going to take to it, some people I've converted have given up cigarettes on day one, others don't take to it at all. So now I would advise one of those very basic starter kits from Safercigs, one Vision, one eGo battery, one charger, small bottle of juice. Once you know it's for you, you can get your credit card out.
