Coming to Heinz field for the first time

I am finally going to make it to Heinz Field in November to see the Steelers play the Carolina Panthers. I am about to buy tickets... what areas are the best and what areas should I avoid. I am trying to stay below $200 a ticket. Do the seats in the end zone sections 122, 123 and 124 good for viewing the game? I am bringing my son with me, who is 24 years old. He is a Panthers fan but I am a life-long Steelers fan, even though I live in South Carolina. Thanks, and Go Steelers!
