ARO for the tank.
Vcat for the battery.
Ego USB for the charger. May want to get two batteries so as to put one to charge, have one in use. They take about 2-4 hours to charge full on. I used the ARO tanks quite a while myself. The coil head assemblies are spot on dirt cheap. A five pack usually running around $5. You can also clean them about two times each. One assembly will last around six weeks that way. I wouldn't suggest a fourth cleaning or more. Switch to a new one. These assemblies can also be rebuilt, though the hassle of it and them being so cheap kind of makes it silly to do.
There's also this
kit from MadVapes. The ARO II uses the same coil assemblies as the ARO. All in they are fairly decent kits to let you have carry about kits. I got lured away from them by Direct Lung hitting on an RDA or RDTA. You might also want to look for the T-Dux 2 & T-Dux 3 tanks. These are similar to the ARO yet use different assemblies for coil. You can use dual coil ceramic cupped heads. Yay. They do offer a mild improvement for a Mouth to Lung hit.
While these may not seem sturdy kits,the point to them is they are cheap. If needed you can afford buying more for them. The tanks I suggest are though fairly sturdy. They use Pyrex glass inner tanks surrounded by metal. Careful tightening a tank to the batteries. Don't want the tank to rip off the connector. (Guilty of that myself.)
