I’ve used: Kodak 5205 / 250D, Fuji 8592 / 500D, 8563 / 250D, and 8522 / 64D. The comments on apug about the weak contrast surprised me, though I may have missed that they referred to home processing in C-41 chemistry. My film was processed by a motion picture processing house. I had commercial 4x6 prints made of the Kodak 250D, and, for me, they’re excellent quality. Contrast is not weak at all, and there is an amber mask on all of the stock I’ve used.
I scanned the Fuji negs; they were the easiest scans I’ve made. Had 8x10s made of a few because of a sale on enlargements from jpg files, and I’m quite happy. Modern cine film is made for scanning; that’s often how it’s used in transfer. The only problem I had was that the Fuji 250D was already scratched, as it had probably been in a camera and not shot. The place I bought it from gave me two 150 foot rolls in compensation for the 210 feet I had bought. I thought this was quite generous, though a 150 foot reel of film is nearly useless for motion pictures, as it’s less than two minutes worth, if I’ve got the math right. That means two things. 1] It’s possible to get cine film for $.14 to $.38 per foot, and 2] You may have to buy rolls of 200-400 feet and break them up for your bulk loader. Stock also tends to fluctuate daily.
I have a few scans from the Fuji 8592 / 500D here:

I am working, slowly, to organise my life and get some scans up on flickr (for the bigger file size). I’ll post a link when I get them up.
EcoLeica, I have a couple of Fuji 64D scans I won’t be too embarrassed to post, but I don’t know if that will be much of a preview for you. I’d guess the Kodak 50D will be very nice as well. Expect it to be sharp, with great dynamic range, and excellent colours. You’re being overcharged for the processing, but (two very important buts) 1] cine processing houses aren’t very much interested in business from guys like us because they have to splice our pathetically tiny rolls of ~5 feet into the 1000 feet + of what they’re doing (PITA), and 2] you probably don’t have much choice. I’ll stick with b/w for home development.
