So I've recently been in contact with a place in Ohio that will develop ECN-2 rolls. They also offer positives on Vision 2383, paper prints, and scans. Prices sound reasonable ($5/roll for dev). They do not appear to have a website, nor have I ever heard of the place before. My brother is in film school in Ohio and has never mentioned a motion film lab in state. So I'm not exactly sure what the status of the place is. Sounds like it's worth a try.
