I had the predecessor to the SL961, the SL960D, for my Canon A80. I was just getting started and didn't know if I would get into it, so I didn't want to invest a lot. Let me just say - I got what I paid for. I was constantly having issues with the SL strobe. I went on 3 dive trips in the time I had it and it worked about 20% of the time. It was not operator error. I sent it back to the manufacturer on two occasions. When they sent it back the second time, they sent me a new SL961. While it looks like a much better set up, you will still need to connect the fiber optic cable to the front of the housing. Sometimes that works, sometimes it doesn't. If diving in strong currents, the fiber optic cable easy comes separated from the housing. I think some fiber optic connectors are better than others, but the SL961 is simply a velcro donut that affixes to the housing with a round disk where the cable is inserted. When I bought my G9, I went for the DS125 strobe. I have taken it on one trip and had no issues whatsoever, srong currents and all. When I was doing strobe research, I didn't think a well-made strobe could make that much difference. Trust me, it does.
