I am a terrible coil builder but the
kayfun lite is very forgiving. Just don't buy the one from ebay, Privatedeal2010. It rusts and the screws strip out very easily. My favorite is the authentic, but I have a couple of EHPRO that are almost just as good. Either way for a beginner, these are really good to start out with. You won't go wrong. If I build a Kayfun, anyone can. To go even cheaper, use cotton or yarn for the wick.
