They are called the Tatroe tanks, I got a couple of them, well still waiting on them in the mail. Decided to get them after dropping and shattering the glass in 4 protanks over the past few weeks. they look very nice.
they are a little pricey compared to the protank but will last a lot longer I think. Only down side is you can't see your juice level. Think they actually hold a bit more than the protank too.
I like the bottom Tatroes, so your ProThingy won't fall over - but they aren't in my budget.
