Welcome and congrats!!
Obsessive?  No, not at all.  Went from a cig-a-like to ego style with Protank, to Provari with PT, then the Russian rba, then DIY juice, got the Terminator-C a Fogger rba, some cheap kayfun clones, then dived into Mechs with the Nemesis 2 tone clone, and then bought the Aqua rba.  Then I just had to order the Origin brass Mech, still waiting on that, and then got the Flashi-e-Vapor V2 rba/rda.  Oh, and got the Arnold also.  Have a gallon of VG, 750 ml of PG, 600 ml of nic base, and a bunch of flavor extracts.  Bag of cotton ball, bag of Hemp fiber and going to get some ceramic wick me thinks.  Also have a couple spools of wire.
Some may call it obsessive, I call it Vape Investment.   Sure I've spent a fair amount of money in the last six months, but next year should be a no cost vape year except for some flavor extracts.   That's of course if they don't come up with something I just have to get. lmao.
