I have been toying with the idea of DIY. Especially since my last ejuice binge was over $100, and looking at what I got doesn't seem like much for the price. Have you ever tried one of those DIY projects and it turns out to be more expensive than just outright buying the vendor version? Happens to me frequently. Which brings me to the question, is DIY really more bang for your buck in the long run? How steep is the learning curve?
