From my lurking and research you've essentially got three options, depending on your style of wick:
Genesis: Smoktech RSST (best bang-for-your-buck)
Mesh: Taifun GT
Silica: kayfun x.x/kayfun Lite
I haven't listed the Ithaka as you need a NR-R (no resistance to resistance) join in your wires which is a PITA. It's a nice vape though.
These are the originals...I know that people have differing opinions on clones, but if you don't mind there's the following to try:
Genesis: RSST (Semi-clone of the AC9)
Mesh: Fogger V2 (75% clone of the Taifun, few differences)
Silica: Russian/Russian 91%/iSmoka Magoo (KF/KFL/Ithaka clones)
There is also a 1:1 clone of the kayfun Lite (the Russian 91% brings a few more things to the table) being released by Ehpro but I've left that out as it's an unknown for now.
If your preference is cotton, I am led to believe all of these devices (save for the Ithaka) work extremely well with it as well.
