Hi Tony, I sold my S1 pro last year and purchased a used "mint" D1. Some of my reasons among many were no RAW image file with the S1 and the lens limitations. Another was the build quality of the S1. I do alot of out doors and wildlife photography and gave the S1 more of a beating than it could handle. The D1 is at a professional level in this respect as well. That's not to say you cannot take great pictures with the Fuji. Everyone's needs are different and I can only tell you mine. Steves-digicams.com has reviews on both cameras along with sample pictures if that helps. Good luck and have fun.
