I agree with many of the previous posters, as to vaping being a lot cheaper than smoking.
Unless you just "have to have" every new and expensive mod. But buying those things is a choice, not a necessity. (Hey.. all those things really do is provide the electricity that you need to power your vaporizer

)
Unless you just "have to have" juice for 1$ a ml instead of the less expensive varieties. That is also a choice, not a necessity.
I have been vaping for almost 2 years, and I have invested some money in decent but not fancy hardware. To me, variable voltage is a must, a Provari is not.

I also started mixing my own juice some time ago, and now I vape tasty juice for very little money.
And one main difference between smoking tobacco cigarettes and vaping (from a money point of view):
-When you purchase cigarettes, and you light those cigarettes on fire and smoke them, then there is nothing left. Your money went up in smoke. But when you purchase vaping hardware, then you have the hardware and you can use it. For months or even years. Purchasing vaping hardware is an investment.
And as to what a person "must have" or not: that is a personal decision.
Some people "must have" the latest BMW, others are more than content with a Volkswagen Golf.
Some ladies "must have" the latest gold and diamond jewelry, others happily purchase some nice costume jewelry and wear it happily. By the way, there are many pretty vaping things for the ladies. And a nice metallic blue battery for 25 Euro makes me just as happy as a new pair of earrings
It is all a matter of personal choice. Every person has to decide for themselves whether the most expensive stuff is "really" necessary to make them happy. Or if decent equipment for a decent price will not do the job just as well.
