You don't need to dump $200 in a Provari. Suggestions that you do are blatant fanboyism.
If you really feel the need for something small, like a cigarette, there are only a small handful of models worth spending a dime on. The Volt is one, the Bloog Fusionmaxx is another and there are a only couple more.
I will warn you that for anyone accustomed to smoking more than about 1/2 pack a day, the long term operating costs of small ecigs is high. You will replace batteries often. You'll probably need several of them as their capacity decreases over time. Buying pre-filled cartridges gets expensive. You're far better off refilling your own cartridges or cartomizers. It's mind-numbing simple. You'll figure that out soon enough.
If you want something with outstanding performance and long term economy, look at one of the eGo types of PV. The kGo and e-Power both get stellar reviews from new vapers. They're simple, reliable, produce plenty of vapor and are units you can stick with for the long term. They're also versatile and there are hundreds of different cartomizers, atomizers tanks and whatnot that you can use them with.
Unlike the cig looking units, the bigger batteries of the "eGo" types of PV also accept low resistance cartomizers and atomizers for maximum vapor production. The only drawback is that they don't look like cigarettes, which is no drawback at all.** Most people get over the need to to have something that looks "just like a cigarette" within a matter of weeks. These "eGo type" units are roughly the size of a Sharpie marker pen and their 1100mah to 3100mah batteries last from one to three days between charges for most people.
The kGo and e-Power both run about $45 for a starter kit. With extra cartomizers and a variety of juice, your total cost is likely to be less than $100, including a month or two worth of consumables, like juice and cartomizers. That's less than half the cost of the Provari that the fanboys will try to convince you that you need.
**Since they don't look like cigarettes, you will find yourself being hassled a whole lot less when you vape in public.
