has anyone had any luck with an e-cigarette? I have one, but it doesn't work well. I paid $75 for it last summer. as it turns out the one with the button is the one to have but I don't know if I should spend another $100. the one with the button actually provided enough vapour that I felt like I was really smoking versus the one I have where I have to suck super hard and get nothing to blow out.

just curious what others think. thanks!
