Hey, those Sunpaks look like a terrific idea. I hadn't thought about using a cord off-camera, and actually I believe the original 480ex won't take a PC cord, will it? I've got cable-able flashes, I've got Canon TTL-capable flashes, but I think the intersection of the two is empty.

The Sunpak module that has the TTL "brains" is standard across all their flashes, right?
