Excellent choices. I see you've done your homework well.
I have always said, once you find the "right setup", subsequent costs need only be for replacement eliquid (and maybe replacement coils if you use those). You can easily save money by stop smoking and begin vaping. Just learn to control the hobbyist/enthusiast/collector aspect of vaping.
I tried a bottom feeding box mod and it wasn't for me. The mods that I've ended up with are a
Provari and a
Silver Bullet mech. I've used both for at least two years on a daily basis. I'm in a happy place in my vaping. I spent most of last year working in a vape shop, and never seen anything that would better suit my needs than my Bullet and Provari.
IMO, the Silver Bullet, Provari, and Reo have been the most durable and best made mods for a long, long time. It's no surprise that all three are made in the USA.
