everything ive read says use stainless, ive heard recommendations from people that say aluminum is fine. Alot of people use aluminum kegs for kettles also so it must be alright. However I bought a stainless kettle.
If you want aluminum, just buy a turkey fryer and it will come with one, plus you have a big A$$ burner to use too.
I saved my aluminum pot for frying...and steaming.
