I just purchased off ebay: 2- Black Kayfun Lite V2 Plus by Ehpro adjustable airflow: for 35.00 ea.
I don't know what a original Kayfun is like, but I am in Heaven with this clone. Works perfect, I did not realize what good flavor and clouds of smoke was untill I got these.
My first try at building my coil was excellent, 1.8 ohms, thanks to you tube.
I have since bought enough 30ga kanthal, and wallgreens organic cotton to last many years. My protanks,evods,viva novas, will collect dust now!!
my next step is DIY juice, I just bought 170.00 worth of nicotine,vg,pg,flavors,sweetner, etc. from My Freedom Smokes.com ( 1 liter 50.00) for nic. not bad!!
