Progressive International Stainless Steel 30 Quart Stock Pot

I was looking for a 30 qt stainless steel pot for canning (I will use it for multiple purposes--sometimes to make acidic soups/sauces, etc., so a cheaper aluminum pot wouldn't fit the bill). This was the best price I could find anywhere online and much cheaper than my local restaurant supply. The lid fits great, love the double riveted handles--very sturdy. My one beef is that the bottom is not as thick/solid as I would like--when filled up, the metal is thin enough that the bottom will bow out (even when it's empty, you can "ping" the bottom in and out by pushing on the middle of it)--made me a bit nervous when it was loaded and I hope the bottom doesn't eventually wear through in the areas where it rests on gas burner grates. Fortunately, the box advertises a 5 year warranty--I plan to put it through the wringer with canning, so I'll how it holds up in the long term.
