Hmm, one grand on vape gear, that's a toughie. Probably a hundred or so in RBA supplies, another $100 on a pair of high-end RBA/tank systems, a few liters of PG/VG (cheap, comparatively), many many bottles of flavoring from MBV and Wizard Labs (basically all the LA/LAN flavors from WL) which could easily be $200 right there for the liquid components. That leaves me with what, six hundred or so? Five or six Protank Minis, few more packs of heads, other replacement parts..actually, forget the PT Mini, I'd probably get the Davide Mini cause of the removable drip tips (yes I know the PTv2 Mini is coming, I'm impatient and after the machining issues with the PTv2 I'm leery), so that's another $100.
Now, the other half..ugh..this is where it gets difficult for me. I guess DNA20 chips would count, so probably two of those, with accessories, that's around $150 I guess.. Three fifty left, I'd figure out some way to cheat the 'vape gear' rule and get electronics bits and bobs for mod-making, that could easily be another $200 right there if I got fancy with microcontrollers, voltage regulators, LCDs, high-amperage switches, project boxes/battery boxes, spools of 16ga copper wire, LiPos...
The last $150 I'd happily blow on VV Egos and Pyrex tanks plus heads/chargers/liquids for my gf's brother and another good female friend of mine.
Also subbing for curiosity, maybe I'll see the name of a new mod pop up in here that I can go drool over. Provaris/Reos/etc don't do much for me as I can build a Provari-level mod with even more features for maybe 70% or less of retail, all I miss out on is the warranty, but seeing as I built it, I can obviously fix it myself too! In no way am I bashing the Provari at all, it's an excellent mod, and I've heard customer service is absolutely stellar, but being DIY-inclined with that sort of thing, I can't justify $200+ on a mod I can build for $150 and have VW as well as a 'mechanical/sub-ohm' mode in addition to everything else.
ETA: Yes, I mentioned plenty of DIY supplies, and no, I did not forget nicotine, I have a half liter of unopened 60mg VG-based nic here that'll last me until I'm off the nicotine entirely, already down to 6mg all day with 18mg in the mornings, so why buy more concentrated nic when I can cut what I have and get 5 liters of 6mg nic?
