Started with a Volcano (l88b/BLu-type) starter kit I bought for someone else, used a little to break in the atties for them, and then didn't give away after all because oops-I-accidentally-quit-smoking.
Moved up to a Modern Vapor Sidesho kit after a couple of weeks, because it was a slight improvement (but still an l88b).
Then I got into 510s and KR808s simultaneously, after a month or so, when my last l88b atty died and I ended up panic-buying a Joye Stick from a local smoke shop and ordering a whole 808 carto kit online "for backup".
Then I freaked out about how much I'd been spending and waited almost 6 months before buying myself a GGTS for my birthday.
Then I got a UFS for the GGTS. Then I got a Penelope so I wouldn't have to keep buying cartos. Then I got some eGo passthroughs to run the Penelope at my computer without wasting all my 18650s, which got me into eGos and the eGo Twist. Then I tried the G-Sub kit from Virgin Vapor because it turned out I really liked variable-voltage vaping.
The sig I set up years ago amuses me now, because it shows how much I've "saved" but doesn't show that I've spent roughly half that much as well.
It makes me happy to see more people starting off with the eGos and such and giving up the "must look and feel like a cigarette" idea, because while any way to quit smoking is a win, my way was... a wee bit wasteful.
