tgs3, the reason I wouldn't buy a spinner for NETs is that's a tiny tank, and your coils will gunk QUICKLY. NETs are really known coil gunkers. You are either going to need a higher power device with coils designed to run high volume, high VG setups like a sub0hm setup, and even then coil life is going to be iffy.
An RTA is a Rebuildable Tank Atomizer. There are tons of them, some designed for MTL or DL. It's a tank in which you build your own coils and wicking. It's much less expensive to recoil once gunked, you simply remove your (cotton or rayon, or whatever type of wick you choose) dry burn the coils that you wind and install (you can get precoiled coils, if you so desire, though those typically can be lower resistance coils, I haven't run across too many higher resistance coils, but I build my own so I haven't really looked, they may be available). Then, you insert your wicking, and you are (hopefully) good to go. They're less expensive than prefab coils, as you won't be constantly replacing them.
Some good MTL RTAs on the market now include: the doggystyle (a clone from FT is totally acceptable) any of the kayfun clones (I wouldn't buy an original until you figure out which one you like, and decide if you are really into RTAs or not) the Vandy Vape Berserker is getting good reviews and is inexpensive, the Siren V2 (not sure if clones are available yet) and I am partial to the Hussar Skx clone (again available on FT, you'd want the single coil build deck and the one that comes with an airflow reducer, but it's an EASY build to start if you get the two post deck) but there are TONS of options.
Might want to check out:
RTA
And:
Coil Builds
These should get you started learning more about RTAs and building your own coils.
I will say I've gotten to the point where some of my builds are successful. It's a learning curve, though to be fair, I have a fine motor tremor and that slows me down. But, I'm getting there, and it can be a great vape, and a great option for known coil gunking factors. Startup costs can be as little as some wick, wire, and a tank, though I found the coilbuilder's V2 kit very helpful and use everything in it (about $30 on amazon) and then the cost of the tank (the kit does come with wire and cotton, but it's not the greatest quality, but it's fine for starting with. It's kanthal wire so you can't use Temp control mode with that wire but to start, it's not super necessary and I find Kanthal the easiest wire to coil with though I use SS myself, nowadays....
Best of luck, hope this helps!
