Jan 2013 began my e-cig 'adventure' to quit analogs forever! (health issue finally made me try again!)
to date:
$551.91 in devices/PVs (batteries, tanks, clearomizers, cartos, starter kit, atty heads, bottles for mixing juice, needles to fill with, etc.), and...
$323.67 in juices/e-liquids/flavorings.
not breaking even yet, but have stopped smoking and that is worth any amount of $ to me

I no longer feel bad about what I've spent because it's a journey to find what is best in my mind for me - and I haven't spent oodles on things that just don't work either. I researched what others spent before I began and knew it was close to $1,000+or- on average for others. I like the fact that things change quickly in what is available 'to try'. We have the 'makers' attention and they're working hard to satisfy us (grin).
