I find it interesting that 220 commends a premium at B&H. I'm in Japan right now and 220 film is fraction cheaper than 120. There's stock of velvia, provia, fuji pro160/400 and 160/400 portras. Maybe something else I have missed as well.
Makes me wish that I had a camera which takes 220 film. Might be time to get a 220 back for my hasselblad.
