As mentioned, the protank with Air Flow Control base is nice. I put an AFC on my ProTank 3 and wow what a difference. All kanger tanks are pyrex. Aerotanks are another option.
What is really nice about the aerotanks; they give you the pyrex glass tank but also give you a SS tank as well in case you break the glass. The pyrex is tough; I have dropped mine a few times and not a mark on it and you can use any juice in it and not worry about it cracking the tank. The plastics are susceptible to cracking with some juices. For example, the Nautilus' tank may crack or degrade over time when using cinnamon red hots and some other juices.
