I've got a Vapor Brothers which is similar to the Vapor Warez. Works great and is a hell of a lot chaeper than the Volcano. People rave about the Volcano but for $500+ the damn thing better blow me after it gets me high. Just stay away from those $50 vaps with the glass dome on top, like the BC Vaporizer. I got one of those first and eventually just tossed it in the trash.
