I've got a Polyscience coming this week, hopefully. A few small questions: I know I can use up to 30 quarts, should I just go buy a big stockpot at the local restaurant supply place, or would a cooler work better? My current shopping list is some sort of food sealer, the aforementioned vessel to cook in, and a ton of ping pong balls for insulation thanks to PedroG. I've got water tight silicone gloves to use in the hot water, and a cast iron pan for searing. Anything else I really need to get started? I want my first sous vide run to be 72 hour short ribs, which is pretty much the reason I bought the thing.
