I am also new to this, but since I live in Oregon and have had several family members buy Ecigs from out of state while traveling, and then they were not able to get replacement carts in Oregon, decided to wait. I just bought a Blu and I'm giving it a try, (Still on the first Cart). I'm liking the Blu so far, but haven't tried any of the others yet. When I get back to Oregon I will go to one of the newly opened vape stores about an hour away and look at what they offer.
