I thought that I had decided on the S2000 to go with my Canon S90 and Canon case. I am a newbie and based upon many recommendations I called two shops that are recommended on this site. As you can guess one recommended the S2000 and the other the YS-01. I used the camera and case for a recent trip to Tahiti and got decent but not great results. I am off to Fiji next month and want to try and get at least few shots that are worthy of enlargement for my office. I only go on one or two trips a year and I am still challenged with all of the camera settings. Would love to hear some suggestions as to which strobe to go with, both are similar in price. Also, does the length of the arms matter dramatically and should I look for one brand of arm vs. another, thanks.
