Great score!  Congratulations on your first ERIE pan.  I regularly cook in my # 9 4th series.  Its too nice a pan to leave on the wall for long.  The 3rd series 10 also gets some time on the stove when I need a bit more room.  I've only ever had the 1st series 12 on the stove once when I needed a really big batch of refried beans.  I was amazed I could one hand the 12 fully loaded with beans!  You are going to have a hard time NOT cooking in yours!  Enjoy!
