I wouldn't mind getting a hold of the Kodak Portra in both 35mm and 120 if no one's spoken for them yet. Also, if you can't find someone willing to take the Superia 120 off your hands, I'd really like to see if I can get anything out of them. I shot some long exposures in 35mm years ago and the colours at night along the beach here came up beautifully. An attempt with 120 on the same type of film would be a great opportunity for me.
Please let me know how much you'd like for those films and I'd be only too happy to send some money your way for them
