I've owned and loved a series of Canon Power Shot Digital Elphs, the most recent SD600. The quality of this Elph seemed less than the others. I also own the Canon Digit Rebel XT that I'll be upgrading to a EOS 40D if I don't go back to my film cameras (I miss the extra crispness of film images but love the convenience of digital).
For samples of images I took with this Ricoh and more information, go to my .mac site.
Popflash.com is having a great New Year's special on this camera which includes the case, extra battery, viewfinder and free shipping.
