Got this for 100 bucks. Is there anything i should do to "tune up" this thing? Want to use it this weekend to burn some meat. I realize its not real pretty but i am not really concerned about appearance. I guess i could brillo the outside. Someone told me to paint it but that doesnt sound like it would last once it heated up. Do these things usually come with a grate in the firebox? Temp guage is fogged. WOuld you guys buyt the stock replacement or go with some aftermarket unit?
