If you're looking for something similar to the STM, check these out. Joyetech eGo ONE Mega V2 Tank
Even has it's own thread.
eGo ONE tank series – CLR coil
I used the STM for a couple years but prefer these now. Flavor is about the same (or maybe a little better) as the STM. Still has the swap and go rebuildable (CLR) coil and is actually easier to rebuild. coils are much cheaper too. Joyetech CLR Coils (5 pack)
If you DL, get the .5 ohm. If you MTL, get the 1.0 ohm (the air hole is smaller on the 1.0 ohm).
