Holy. I picked up a good cast iron frying pan in a store in Montreal for 25 bucks a year or so ago.
Cast iron is the shizzit. I have a dutch oven cast iron pot (an old Findlay 8) I inherited from my grandmother via my mom. It is at least ninety years old and as good as the day it was made.
My mom has told me several times that she regrets giving it me.
