I have read up on vaping mostly watching videos on youtube to get to know more about it and I wasn't sure which one to get. I had my eye on those box mods and the ones with the tanks where I could replace the coil and wick on my own without having to spend more on those parts. I assume those will last longer and I would only have to spend on e-juices?
Thanks in advance
As
@DaveSignal said, it sounds like an RDA is the right path for you. There is a slight learning curve compared to a tank with disposable coils that you can just fill & go, but the work is well worth it. With the supplies I have on hand (wire, wick, juice) I could easily go a year or two without purchasing anything -- a comforting thought in the event of a vapeocalypse.
For first devices the iStick 30W is definitely a good place to look. I'd recommend the 50W but some people reported technical issues in the beginning (although that seems to have tapered off). If you're looking for more power straight away, which may prevent having to upgrade in the future, I'd say skip the iStick and jump straight to something like the Sigelei 150W. 150W is more power than most people ever need, but it's nice knowing that the power is there if you want to try and utilize it. My Sig150 is pretty much my daily driver, and with 2x 18650 batteries it
easily lasts all day.
In terms of what RDA to buy there are literally thousands of options, all of which have their own pros/cons. Something like a Patriot RDA is pretty simple and good for a first-time builder. The Twisted Messes RDA is also a really nice authentic RDA (at a decently low price) -- it offers every feature any high-end atomizer will have. Alternatively, there are a load of clones which work fantastically (at a fraction of the cost of their authentic counterparts). I have a Tobh clone as a stand-by, but other options would be things like the Dark Horse RDA or a Plume Veil clone (though I hear mixed reviews). The Derringer is also good, but it's a bit tougher to build on given the reduced chamber.
Anyway, I'm sure plenty of people will chime in with loads of conflicting recommendations. The more you can tell us about your budget/what kind of experience you're looking to get, the more we can narrow down our recommendations.
