Richard,
Having used a first-generation Sony cyber-shot during our cruise in Alaska, I am thinking of upgrading to an ultra-zoom digital, especially before our cruise to Australia/New Zealand November 2005). For what it's worth and after some research, I have become very interested in the Panasonic FZ20 or possibly the FZ3 if I want something a bit more compact. I am not a serious enough photographer to go for an SLR.
