If you want a nice, sturdy tank, get a phiniac. A little more pricey but available in sandblasted or hand-blown designs and the tanks are pyrex, so they won't crack from harsh juices like Cinnamon. Nice tanks, standard sizes, the tall-boy will fit a standard tank cartomizer. If you have specific size questions you can email them. I did, got a response back within an hour with a size suggestion for my tank. They look great, too.
