Well, I finally got my hands on an SU-4 remote flash controller after two and a half months of calling to find one in stock. I've been favorably impressed by this $80 plus shipping 2"x2" piece of plastic (I'm not really complaining about how small it is - I like that). The manual says it may not work in direct sunlight but I took it out for a test and so far mine seems to have done so. I got some pics back and they look like it worked although I was using two flashes outside in daylight (I am seldom organized enough to systematically test equipment but to my eye they looked right - I'll learn more as time goes by). I like the little sound it makes to let you know if the flash: 1)fired; 2) fired at full power; and 3) is ready for another shot. While it may not be loud enough to be heard in noisy environments, on the other hand it is probably not so loud to be distracting (nerve-wracking) in quiet portraiture circumstances. You can cut it off for weddings etc. The shoe connector on top revolves, so you can easily turn the slave window around to face the master flash. The slave eye also revolves up and down. Nicely designed - as you'd expect from Nikon. A little diffuser card on a plastic arm comes with the SU-4. In certain circumstances you would want to insert the arm (looks like a toy crane arm) into your camera's flash show and flip the diffuser down over the flash to cut the light output of a built-in on-camera flash. All in all it seems to be a very handy item. In my opinion and for my purposes, Nikon cords generally seem to be too short. I'm always pulling flashes over in their stands. Once you set them up, it's trouble getting around them etc. The cords will still come in handy. You can still use the SC-17 to take the master off camera, and I guess you can use the SC-19s to hook up second TTL slaves if you like. Richard
