The concord pots mentioned above are what I'm looking at. I got a step bit on amazon for like$10 pr $15. You need a little patience but adding a weld less valve isn't that difficult and can save you a lot. I'm doing 5 gallon batches now and moving to AG so I'm looking at maybe getting a 15gallon pot in case I decode to move to 10 gallons. I don't really see myself going more than that.
