Chinese made? If so, report back on how you like them. I have been toying around with picking up two and building a self contained cooler jockey box.
I think the 60 dollar ones on AIH are the all metal bottoms correct? They look awesome but id be worried about how well the metal holds up to normal handling over time.
I wonder if you could coat the bottom in some sort of polymer, like that liquid truck bed lining stuff just to give it a little renewable durability.
They're my first kegs, so I don't have a lot to compare to. They seem solid, but not indestructible. They will stack, but not with disconnects attached. I had to tighten a post on one of them, but otherwise no leaks as far as I can see. I like the low profile because I only have a small (5.1 gallon) chest freezer and fit four (two tapped) plus a CO2 tank without modifications.
The powder-coat idea sounds interesting. It might be worthwhile if they get banged around a lot. I forsee them getting dinged easily, but could withstand a little abuse. The ring that the dip tube sits over seems solid, and that's the only place I'd be worried about dinging up.
