Hi and welcome! Please tell us a little more about yourself so we can give you useful recommendations - such as how much you smoked and what your lifestyle is like. A person who only smokes when he's out at a bar with friends; a nurse who can only take a short break during a shift; a long-haul trucker and a freelance designer who works at home, all have different requirements.
Your budget is also a big consideration. You will have to buy a power source (batteries), a few delivery systems to try (they hold the liquid and delivers it to the heating element which makes the vapor), a charger and some different flavors of juice. You may be able to find a kit with those components it is, or you may be able to get a better price buying them separately. You can easily put together a good set-up, with everything for around $75.00 (or less)
I strongly suggest you take recommendations to buy the "best," right off the bat with caution. What's the best is subjective and you have to be willing to pay $150 to $200+ to get enough of the above described components to get the benefits. And that would be for the barest of bones.
A Ferrari might be a great car, but if you don't know how to drive, don't have any left over funds to buy high octane gas or insurance and really only wanted a car in the first place to drive to the store, it's kind of overkill.
