I'm in the market for a stainless steel lid for a 5gallon brew kettle. It's the same 5 gallon economy pot that NB sells, but I just need the lid. Maybe you've upgraded and dont need it anymore, let me know what you have.
What's the diameter on the top? I know that wal-mart or target sells universal lids. They look like this http://http://www.chefscatalog.com/product/24305-Universal-Lids.aspx?sourcecode=AW1CS1006&srccode=cii_9324560 &cpncode=20-28327616-2
This one is more expensive than the wal mart one. The one at wal mart or target costs $10-$12. I use it on my keggle, so that's about a 12" diameter.
