Well, you and I will have our eggs in the same basket.

I've gone with ProVari's, but I found (bought) them in the first 6 months of starting to vape, and I don't have a single qualm going forward.
ProVari is a safe basket to place your eggs.

When I say that, I'm speaking of their tube mods. I don't know anything about their other styles...I'm sure they're fine too, I just don't personally have any.
I also have 2 Reos. Not everyone wants to spend that on a mech, and I completely understand...just listing my basket.

I also have a few ego vv/twist types, but those I don't count on for long term anything.
And one other mech, a KTS that a friend sent me.
Good point! Any atty that draws air from the bottom.
