As far as what you need to start
vaping, it depends on what will fit into your life most seamlessly. What are some of the things you are looking for. A PV that is similar to an analog? Something small so you can stealth vape? A two piece
device for convienence, or a versatile
mod. Basically, it would have a lot to do with what you are replacing. How you smoke and what you would feel comfortable with. There is a pv guide for noobies. I'll try to find it and post the link.
