Hi! +1 to
@Falconeer, there's no reason not to duplicate your set up if you like it. Or, you could use it as an opportunity to experiment. Try something different-- a Kanger Topbox kit leaps to mind-- and whichever one you like best becomes your main rig, while the other is your backup.
I also agree with
@Shawn Hoefer, an 18650 tube mech and a couple spare batteries is useful vapocalypse stash, and will keep you going when times are hard. Frankly, mechs are no longer the best choice; regulated mods are easier to use, more flexible, and safer. But it is really hard to break a mech, so long as you keep them clean, and that's also useful. Mechs can not be used to their full potential with prefab coils; you have to build your coils as this is the only way to vary the vape. But they work just fine with prefabs, and are safe enough so long as you stay away from faux hybrid top caps, use good, 20A batteries, and don't try to put a coil below about .5 ohms on a one battery tube; they simply can't deliver their full range of potential like that. It's easy to spend hundreds of dollars-- thousands, for some rare customs-- on a top quality mech, but I would recommend you avoid that and leave it to crusty old mech-heads like me. It's hard to beat a Nemesis clone-- I have 3, and vape them all the time-- and you can buy one from Fasttech for $15. Another good clone is a King V2, about the same price. For an authentic, the Wotofo Phantom (
CAUTION: it comes with both standard and faux hybrid top caps; always, always use the one with the center pin!) is available under $40 and, if you look around for a sale, the Council of Vapor Kindred V1.5 can be had under $50. Both of them are excellent pieces of gear.
