Well, it's hard to say what you might like, since this is your first foray into vaping. Given equipment may be hard to find where you are, I might consider a two battery mod that you can get good life out of, whether you smoke MTL (smaller volume of vapor, higher nicotine level, usually at or above 1.0 resistance and more like smoking a cigarette), or DL (subohm so less that 1.0 resistance, higher wattage, more vapor, lower nicotine content, and inhaling directly into your lungs like a straw.)
That way, you can choose a sub0hm tank to see how you like it, versus a MTL atomizer (which can easily go on whatever box mod you choose) something like a Nautilus two, or an Ego Mega One V2 (but the joytech CLR coils at 1.0 resistance, they would need to be purchased separately but they fit that tank. I don't really have a great recommendation for a sub0hm topper, I vape MTL. But to me, that looks like the most efficient way to get what you need, as you figure out what you
want if that makes any sense.
You do also need a source for authentic batteries and a charger if you are using external batteries that are typically removed from the mod to charge elsewhere. That may be one of your biggest difficulties, finding authentic batteries, but it is important to do so.
Best of luck, and welcome to ECF. The right juice (correct strength, a flavor you like, and at the right PG/VG percentage will also be important. You may have to do some experimenting there, too.
It can all seem a bit daunting to start, but the main thing is to develop a plan, then implement it in stages. You will find your vaping "nirvana" somewhere along the way.
Best of luck, and welcome
