Wow, that's comprehensive, Tommy-Chi! I'm a little more hit-and-miss, but I have 5 provari Minis, 1 provari P3, 2 eleaf 30w, 2 e-pipes, a Reo, and a bunch of cigalikes (from when I began vaping). I need lots more atomizers, and I don't know which ones you can easily rebuild the coils on; I've never tried that. I just got a quart of 50/50 0 nic base, which is going in my freezer in glass bottles. I also am getting some flavorings, but I know their life is limited. Fortunately, bakers and the rest of the food inductry will always need flavorings.
