Like most of the other's who responded, I started out by finding a few recipes that fit my flavor profile and bought the stuff to make them. I also bought the flavors that I determined I needed to make a clone of my favorite commercial juice. I guess I ordered maybe 6-7 flavors, VG, PG, and Nic, and a few syringes. Trust these guys, and don't waste your money on a starter kit, it's cheaper to just buy what you need individually.
