For me its about a 3 weeks to break even?
$40 a carton in VA (which is cheap)
I spent about $160 - $200 a month. I could go crazy buying PVs for that money.
Since money is tight right now I've kept my spending to about $150. I should have enough juice and parts to last another month too.
The parts seem to last longer than I thought. I'm now expecting to spend $20 - $40 a month for fairly heavy use. One part + 60ml juice per month.
To be fair, the 510 and juice is all I need to replace cigarettes. I would like to try some other PVs once I get some extra money to burn (vaporize).
A lot of guys on the forum are kinda hobbyists and have tried most of the models and juice flavors. To me that money doesn't count since they are spending extra money on a hobby not so much the habit.
It really helps to get the right equipment the first time. If I had fallen for the SE kit I'd be $150 in the hole and maybe still buying cigarettes.
