If you want something authentic, go for an Expromizer. The machining isn't as good as an authentic Kayfun, but the vape quality.... It's really pretty great. Better, dare I say, then a Kayfun. I just got one yesterday and was blown away. I was disappointed in the machining on opening the box, but once I cleaned it up and got a coil in it the disappointment vanished. I had to give it to hubby, but I'm going to keep my eye out for more. The best price I've seen so far, from a USA vendor is VapinArt.com. $65 or around that. I believe they have the extended version still in stock for around $80, but the standard one is sold out right now.
It's easier to deal with then a Kayfun. It can be filled like any bottom coil clearo, without the need for a screwdriver or a needle tipped anything. The airflow is controlled by a ring for which there is no need of a hex screwdriver or a regular screwdriver. The juice channels are deeper to allow more juice to flow to the coil.... I love the overall design. I actually hope someone like hcigar or Ehpro clone it and get the threading right, as the threading is pretty choppy in areas.
