would be my recommendation. Less than 6 bucks for a roll of 120 E-6 processed. Not sure about shipping costs, as they are local to me. But they do fine work. Just had a roll of E100SW 120 done last week, from my Moskva 5, 6x9. Talk about stupendous transparencies! You can call them at 800-445-0264.
