Just get any old temperature-controlled box mod, like the e-cig style vapers use, and then order yourself a Saionara atomizer from Divine Tribe. When you are picking out which type of coil you want, decide whether you want to take huge rips or if you want to micro-dab. If huge rips, go for a triple coil. If you are a sipper, go for a single coil. And go with stainless steel, so that it can be temperature controlled. Then, set your box mod to around ~350-400 degrees F, at about 25 watts, and have at it.
Since I'm not into taking huge rips, I have never invested in a dab rig, nor do I feel the need to. The Saionara was like $35 or something, I don't remember. A 5-pack of coils was like $25 or so. Each coil lasts me about a week or two before needing to clean it, and then I can soak it in isopropyl alcohol for a night, dry fire it to clean it, and get another use or two out of it before feeling like I should just trash it and pull out a fresh one.
The box mod I use is an E-leaf iStick Pico.
