nice you just can't beat Cast iron.
I have picked up just about all my cast iron from garage sale.
people sell them really cheap. the most I have paid is a few dollars.
Some of them were so disgusting, people looked at me and i know they were thinking " Is she serious" I put them in boiling hot soapy water to soak, then hose them off with the garden hose, then I have a wire brush that fits in my cordless drill, wire brush all the crap off of it till it is all smoothe again . give it another sudsey washing.
heat up the gas grill and season it. You just can't hurt cast iron. I got a 7 qt dutch oven for almost nothing!!! I also got the cutest lil fry pan that you could do 2 eggs in it for a nickel. I have many many peices now.
One day your life will flash before your eyes. Make sure it's worth watching
