Well, I keep a running tally of ALL my purchases. Batteries, chargers, juice, kanthal, etc... along with devices/toppers.
Dove deep into vaping at the beginning of last month, and have spent $1,150.00
Two Nemesis mods, 4 RDAs, multiple eGos(just a stepping stone now), Kanger tanks, tons of juice... and on and on. Seems like a lot, but this is honestly the first hobby I've found that I can fully jump into like this, and ONLY spend that much. Try national level ATV racing, big-block round body Suburbans, or even Nitro R/C cars......which have been sidelined for years now, for that exact reason.
