O.K. I went through this entire thread and can't believe there's arguments over which crap product is the least crap, and not a single mention of the obviously superior product. Like you guys have never heard of this material called metal.

Looking for at least a 1.5 gallon rectangular container? Oh look:

It's not that hard guys.
