when I was at TAP last I saw a ~50gal container getting loaded into the back of someones truck, it looked like a small version of those white plastic ones you see holding RO/DI and premix saltwater at LFS. Had the spigot at the bottom and a big screw at the top.
I'm guessing they cost 10x more than Brute, but they sure look nicer, cleaner, and more mobile.
Cheers,
Josh
