Yep, I have a few tanks - once I learned to stop breaking them (the top of the truck, refrigerator, etc. is not a place to set them) I settled in and bought quite a few of a couple of types that are all interchangeable and work fine for me.
While firmly in the same " camp " as Semi, can't quite say the same regarding my hardware. I started with fixed voltage egos and replaceable head CE types. Moved to VV pretty quickly, then into PT, Evod and T3S toppers. And so on.
Now, most everything is replaceable 18650 mods and kayfuns. LOTS of both, thanks to the FDA!!
Yep, I am pretty set and like David - I got no reason to change. I am not going back to cigs (never) and that is the mainstay in my life.
I did my latest upgrade with a few kayfuns lately myself.
