If I choose a set, how can I know if atomizers will still be available for it later?

I know it’s an old chestnut… but for preventing atomizer problems, the best/simplest/cheapest solution is building (coils).
2 simple RTAs that suit your needs, minimal tools required, 50m of wire and a big bag of cotton will probably be enough for the rest of your life.
And it’s really ridiculously easy to learn too.
