Electric cigarrette to help quit?

Now I don't smoke addictingly, more habitually, and when I do I can feel it, which to me is a good thing becuase it has a physcologically effect that I should stop, but I keep coming back. I'ts become more habitual at this point. I can do without them, but sometimes I have these cravings, and I think it's the oral fixation and actual smoking itself that's become addicting, not the tobacco. I've tried switching to non-additive natural tobacco such as Nat Sherman, but they dont' run cheap and it wouldn't fully solve the problem. I've had an electric cigarrette before but it didn't really give off the amount of smoke (vapor) that I would've liked, but it tided me over till I ran out of cartidges (a friend had let me try a free one). lately iv'e been a stress smoker and marlboro smooth and nat sherman have certainly helped, but I know it could only get worse. I guess my question would be what electric cigarrette would be closest to the smoking experience? high volume of smoke (vapor), taste, feel, etc.?
