I've used these 12 qt pots from Bed, Bath & Beyond in my ren faire kitchens for years, same pot but they used a different "brand" name for them when I bought them. They hold up well. I've made countless soups in them. I've used them on regular stoves and 30k BTU camp stoves, they can take it.
I have both the pot above and the ones with the pasta insert. The pasta insert works very well for steaming large amounts of veggies, hard cooking 5 dozen eggs, etc.
