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.
