[...] Mind you, the marketing of most mass-market e-cigs are extremely optimistic when it comes to the cartridge life. A single cartridge of one of those is more the equivalent of 6 or 7 normal cigarettes than 20.
If that; I'd say lower than 5, in my experience. And that's just quantity-of-fags equivalent; I'd be amazed if the amount-of-nicotine equivalence claims are accurate, too.
[...] Still, the lack of a "finish" such as when your usual cigarette runs out is an issue, but for those who can't seem to put them down, you can always lower the nicotine strength of the liquid. If you begin to notice adverse effects or symptoms of too much nicotine, then adjust your habits or lower the strength. Common sense.
Indeed
From these vaping threads, two things are increasingly evident:
- Most people wrongly think it's the nicotine that makes smoking an extremely harmful pastime. Clearly, those old Superman posters just wanted to scare, not educate. Who'da thunk it?
- Most people are unaware that nicotine-free vaping is an easy, realistic option for those making the transition from smoker > vaper > total liberation. Or even those that don't want to let go of the physical aspect of inhaling from something you hold.
Still, the more threads on the subject, the better.
EDIT: Oh, and to answer the OP, I'd go for something like the Riva-T, also known as the Ego-T, or the 510-T kits - if a more cigarette-dimensioned device is preferred - from a decent store [Liberty Flights, for instance]. I wouldn't recommend the equivalent from Totally Wicked, as pretty much everything I've ever bought from them has been shonky [including the free TW pen they chucked in, which didn't even write

].
