Coming from exclusively using drippers I am now looking for a tank that covers all bases. Ideally I want a tank that has great sub ohm and temperature control disposable coils but one that I can also rebuild when I run out of disposable coils. The only tank that I have found that does all these things is the subtank now that they have released the TC nickel disposables. Are there any other good options, preferably something with cheap easy to find disposables?
