Vandal, first I suggest you get familiar with pretty much state of the art hardware. Theoretically, you have a couple of months to do this before internet sales disappear, but I sure wouldn't take that much time. Find your "sweet spot" — quick! Find something that works for you, not the newest, wowiest-zowiest hardware.
Next, here's what I suspect will disappear via the Deeming Regulations, assuming they aren't changed. And these are just my opinions; your mileage may vary.
1. High-test nicotine concentrate. This is the ultimate choke-point. Buy as much as you can of 60 or 100 mg./ml., put it in glass bottles, and buy a chest-type freezer to store it at -10 to -15 degrees. Do this FIRST. I have enough high-test in my freezer to last until I'm about 95 years old.
2. PVs: I'd ignore the combination eGo-types. Batteries, charged or not, die within a few years, and there's no way to bring them back to life. So, if you're using a PV with enclosed battery, the whole thing is dead. (Want some dead five-year-old eGos?) Look for a PV with a removable battery or batteries. Then you can use fresh batteries without having to chuck the whole PV.
There are regulated PVs (like Provaris) and unregulated ones (like Reos). I have both in my stash. The electronics in the regulated types may eventually die; unregulated just need hardware replacement every so often. To be safer with my regulated ones (ambient humidity is no good for electronics), they're in cryopack. You can get a cryopack bagger and enough bags to last a lifetime for about $55.
3.
tanks, or whatever: Find one with potentially rebuildable
coils. I've recoiled Vision Vivi Novas, and the Nautilus-type actually look a bit easier to recoil. But that's up to you. Some folks say purpose-designed rebuildables are easier to recoil. Buy several different types, then follow instructions on youtube to see which works best for you. Note that supplies to rebuild these will be around about forever: they're used for other things. I like Nautilus, so I have 40 of them in my stash, plus 60 pyrex bells (for breakage: I can be a klutz) and about 200 replacement
coils. Kanthal wire and wicking (cotton, rayon or whatever) will be around forever: different uses.
4. Search for flavorings you like, ones that are available as jelly-bean and baking flavors. Learn to DIY: there's an extensive bunch of threads and how-tos on ECF. Download a DIY calculator NOW. The FDA has probably banned these as well.But the flavorings will be around forever: again, many different uses.
5. Batteries: 18650 and similar batteries will be around forever, as they have so many other uses. For instance, Tesla cars use a whole bunch of 18650's or similar. Get a good, plug-in-the-wall charger.
I'm a belt-and-suspenders kind of person. But, if I read the Deeming Regulations right, this is truly Vapemageddon. Better to be stocked up than sorry.
