Wow, I've played or ran almost every one of them on that list:
I1: Dwellers of the Forbidden City (tried running this as a PBP on the boards here in the the last year, but the game failed)
I2: Tomb of the Lizard King
I3: Pharaoh (a great classic)
I4: Oasis of the White Palm
I5: Lost Tomb of MarteK
I6: Ravenloft (an all time favorite, ran multiple times)
I7: Baltron's Beacon (another all time favotire, ran multiple times)
I9: Day of Al'Akbar (fun in the sun and sand)
I10: Ravenloft II: House on Gryphon Hill (underrated; I thought this was a fun adventure)
I11: Needle (IMHO, one of the worst adventures of all time)
I12: Egg of the Phoenix
I14: Swords of the Iron Legion (I really enjoyed this one as well; as a campaign, it wasn't quite that great, but some of the individual adventure's were great)
Out of those that I've ran/played, I've got all of them EXCEPT I2 and I12 still sitting on my shelves.
