I got a pretty neat cooler for the mash tun! It is a 60qt cooler on wheels, and it actually has a small shelf sort of in the bottom and the drain plug is above this shelf so the grains should stay below the drain plug and give me a nice run off with very little grains even though I am going to use the stainless braided hose as my filter like on cruises' site. Found this cooler at Wal-mart for $29. My question is though, where can I find the 7/8 rubber stopper like he mentions?
