I would avoid volcano. They don't seem to stand behind their product. I had bunch of issues with them and they just don't respond when it doesn't suit their needs. I've also noticed their ecig is behind the curve in terms of tech and overpriced. Case in point they came out with "bottom coil tank" last week like its a breakthrough innovation. Realistically this has been available for ages from kanger and other suppliers. Their replacement parts are also way overpriced even though it appears to be made in china like all other ecigs. Just look at at their replacement atomizer prices. At least 50% to 300% more than comparable products. I'd look into starter kits from provari, innokin, or joyetech. They're all around the same price point, have easy learning curve, and replacement parts are non-proprietary so it's cheaper and more reliable.
Also, I noticed volcano only provides plastic tube tanks so it melts when you put most ejuice in there.
