I started with a Magnum from volcanocigs.com about 2 months ago. It's your basic 510. What sold me was the warranty (1 yr) because I noticed the amount of short warranties that a lot of these companies have. They're based out somewhere in Hawaii, but the shipping was reasonable. I wouldn't recommend going for the smaller version of the volcano if your trying to get off analogs, or anything smaller than a 510. I'm also looking to upgrade to an Ego (just had a T-Rex crap out on me) and the best deal I can find is at vaporjunction.com for the Riva kit for $50. They offer a 6 month warranty on the charger and cones. 3 month warranty on the batteries and are located in Alabama.
