Anyone have a conversion kit for a 5 gallon rubbermaid cooler? I am looking into wanting to start partial mash brewing with going into all grain brewing down the road. Thought I would see if anyone had a used set before buying online. If you don't have a set to sell but can recommend a set online for me to look at or have advice on where to look that would be appreciated. The closest LHBS is about 2 hours away.
