Jambalaya Pots...
I have the 10 gallon bayou classic and the stand that came with it. I don't use the stand. I sit it directly on the banjo cooker and have a shroud we built to control wind. If I had seen the first set up in your list, I would have bought it.
The biggest thing I'll tell you is to buy a bigger propane bottle than the standard recycle bottles. I use a 40# for my crawfish cooker that BigE built and for my pot.
