This guy seems to have quite a number of stainless pots in different sizes, but the one that caught my eye was an 11 Gallon Stainless pot with clad bottom for $59 + shipping. More than a few.
Seems he's also got 18 gallon pots at $99 + shipping. More than a few.
Disclaimer: Not mine & never bought from the guy. Just saw the deal. He's got other stuff up for sale, but the pots are @ 1/2 way down.
