I've smoked e-cigs for about two years now. There are A LOT of bogus, overpriced ones out there. If you get a junk one, you will regret it and it will not work well for you.
I recommend:
Smokeless Image Volt
Standard eGo - get cartomizers, NOT a tank system or atomizer/cartridge combos.
There are tons of flavors out there; you will need to try many different ones to find what you like. Note that NONE taste like a real cigarette. Personally, RY4 with my Volt is my go to combo.
Some good websites for gear:
libertyflights
madvapes
Good luck
