I have an SB600 that I bought on here from the original owner a year ago. I bought it for my son's girlfriend. She never used it, they broke up and I got all the gear back. It has been on my camera long enough to make sure all functions work, which they do. There are a few superfical scuffs on the top which were on it when I got it and can be seen in the last photo. I have the box, the manuals and the case. I have bought and sold several items here with no problems of any kind. $185 includes Paypal and shipping to verified Paypal address. CONUS only.
