The Canon SD600 and SD630 are good choices.
You will find that the image is better and sharper than you old SD400.
The SD630 has a larger LCD but no viewfinder.
I had been very happily using a Canon SD400 ultracompact digital camera for about a year before it was recently rendered inoperable by the notorious e18 error.
I am now looking to replace it. I have looked at the SD600 and SD630, both of which i like. I was wondering if anyone could help with deciding whether to stick with canon and get one of these models or to switch from my longtime favorite.
Im looking for a 6/7 MP ultracompact with good image quality for about $275 or less.
thanks in advance.
