You listed two cameras that are in different catagories:
The Canon S410 is a point-and-shoot camera with few manual override features.
The Konica-Minolta F100 was introduced about 2 1/2 years ago. It is an intermediate camera with all the manual override features.
By the way, either would be a good choice.
But I am not sure which type of camera you are looking for.
You might also look at the Kodak DX7440.
It is an intermediate camera with manual override controls and sells for $300.

I'd really appreciate suggestions asap, as I need to buy in the next day! Looking at Canon S410, Konica Minolta dImage F100 (used, much better price), others. Maximum price range is $350 including the 256 mb memory card.
