Ektagraphic, are you sure it's ECN-2 film? (Note it's ECN-2, not ENC-2; that could be the cause of some of JohnRichard's troubles finding information.) Dale Labs did indeed respool this film in the 1980s, but they switched to ordinary C-41 film in the early 1990s (definitely before 1994). I haven't used their services more recently than that, though. It's possible that they're selling small-roll ECN-2 films again, but I'm skeptical of that.
Concerning the development process, this APUG thread has a mix-it-yourself formula that's probably better than buying tens of gallons of the stuff ready-made.
FWIW, I used these films (or their predecessors) in the mid-1980s and eventually grew disillusioned with them, at least for still photography. I wouldn't discourage anybody from trying them if they're curious, but IMHO they are, at best, no better than common C-41 films for still photography -- at least, for typical purposes. I suppose if you're after a low-contrast print they might be just the thing.
