Without a second thought, I suggest you a Dicodes Dani Box, possibly with its charger. With Provape gone, Dicodes is the natural replacement. As distant second, buy a Yihi ML class.
There are no better
tanks than the Kabuki which use a pre-made coil. Its laminar airflow remarkably improves the flavour, while the massive steel base, together with a tight thermal coupling with the coil, double/treble coil life by limiting the time the cotton wadding is staying at higher temperatures.
The Aspire Triton mini is not a well known
tank, but it is a piece of engineering excellence -well worth a try for 25 bucks. Use the 1.8 Ohm Nautilus coil, with optional guitar-wire if you wish.
After the Dani Box, I suggest you:
1. to learn coiling and wicking, it easy and cheap, it is not a challenge, sewing a shirt button is much more difficult.
2. Buy a Kayfun Prime and coil/wick it with the skills learned at point 1.
3. Thank me when you get the best vape in the world, after a couple of months of use.
I say so because, IMO, you may not get any better vape with any other tank which uses pre-made coils. The Kabuki was the best in its class when you bought it, and has remained unchallenged. On the other side, MTL RTAs have improved noticeably, and there is a variety now available. Other than the Kayfuns, there is now a second line, which include the Berserker and the Siren V2. They are very good but not professional in their design (they lack liquid control and have high tolerances, but are much cheaper than Svoemesto, Rose, etc.).
Hope this helps,
