It's amazing what a search on Google will bring you on APUG. I just processed my first two rolls of C-41 film (Superia 200) yesterday, and I was thrilled with the results. But after the film dried I have an abundance of drying marks all over the film, probably from the stabilizer. So I'll use the sponges next time.
I used the JoBo Press Kit, and from what I can tell, besides the drying marks, it worked really really well. It would be interesting to know if there is any difference in ultimate film quality between the various C-41 kits out there.
