I think that vapers go through stages and start out with a basic setup, then get more and more gear until they end up with one or more of the primo PVs, and therefore spend more than they would have had they gone right from the basic to the deluxe setup. There is a lot of gear out there and people have whole collections that could fill up a kitchen table, and even upload pictures of them.
Especially if you have quit analogs you might see all that money you saved and then go on a spending spree. What you want to do is move from wherever you are now to the top of the stairs, not step by step but in leaps. So what I hear from people is they think spending $250+ on a PV is crazy, but they end up spending a lot more than that before they decide to go for the more expensive PV.
In the end what we want is something where we can control the voltage, called VV units. With normal units you are stuck with the battery power, in volts, and whatever the resistance of your atty is, in ohms. Together this defines the wattage that you will vape at.
So people then might look to get lower resistance atties, to bump up the power. Once again though this sticks you with a particular power setting. So what you really want to do is to be able to dial up whatever power you want. Some units, like the Provari, allow you to dial up the voltage of your battery and control the power of the vape that way, and others like the Darwin allow you to control the wattage, meaning that you can set it to a certain amount, say 8 watts, and you'll get that every time, whereas with other VV units you have to adjust the battery voltage with different atties that you use.
There are other types of VV units and people no longer have to spend a lot of money on them, but as a general rule, the more you spend on something the more you get for your money. This might be ease of use, durability, or whatever. So if you're looking to spend less over time, spend more now, because if you don't you will probably be spending even more by being too cheap
