I think there is something to the journey. I started with a V2Cig and I won't call it crappy, it helped me quit smoking in a week. There is nothing crappy about that, no more cigarettes. From a pack a day, to nothing, in a week.
After 1 year I will have not smoked 7300 cigarettes. 7300!? That's insane, until I started to look at how many cigarettes I actually smoked, I had no idea, those full ash trays, that nasty smell, the black funk in the bottom of the trays, oh my god, that's in my lungs man, that's insane.
I went from a V2 to a Tornado Tank, from the Tornado to a Lavatube and just bought an ePipeMod in about the span of a month. I am a supernerd, so all this stuff is overly interesting to me, and I enjoy the fun, but I spent about 2x as much as I had to. I will however still save more than smoking by the end of the year, a lot more. Something like $1000. That's a big deal, especially since I just had a baby 6 days ago, that's a lot of diapers.
I think each of my devices has their place, I use the V2 when in public (bars, restaurants, etc). I use the Tornado when I'm at friends houses or closer social situations, and I use the Lavatube at home.
I did this breakdown for a friend today...
Up Front Costs:
Knight Rider: $89.97
eGo-C: $67.99
510 eGo: $29.99
ePipeMod: $150~
Tanks: $12.99 x 3 = $38.97
Total: ~$400.00
Recurring Costs:
Cartomizers: 2.95 (1 lasts for a week, you have 3 tanks, so you should still only need 52 or so for the year) - $153.40
eLiquid: 1.5 ml per tank, 1 tank a day, 36ml = $16.95 for the good stuff, which brings you to 24 days per bottle. Thats 15 bottles a year, thats 15 * 16.95 - $254.25
Total: ~$450.00 (allowing some room for variance in smoking amounts)
Year 1 total: ~$850.00
This might seem like a lot... but smoking cigarettes, assuming you steal all your lighters from your friends...
$6.50 a pack * 365 = $2372.50 - This assumes you are a pack a day smoker.
If you quit right now, in 365 days you will save ~$1500.00, in 2 years you will save ~$3500. That's just simple math you can't argue with, not to mention, this is way more fun than smoking cigarettes.
