We got an A410 because in Canada - everything is more expensive. Amazon won't ship to Canada, and other companies want to charge over $80 to ship it!!!
So, we went to Futureshop and purchased one - there was about a $75CAD +tax (15%) difference between this camera and the A510. Since we are simply wanting the camera for personal/family use, we couldn't justify the nearly extra $100 in cost to upgrade to the A510.
Needless to say - we LOVE the camera. It takes very crisp pictures, and in vivid setting the colors are amazing. I also am very pleased with the macro mode.
We bought a rechargeable battery pack, but so far, even though I have taken scads of photos, we are still working with the original batteries.
I am honestly surprised it takes as good of pictures as this for the price. While we knew we were getting a good camera, it's better than we had anticipated.
I do suggest not using standard auto mode however, but instead go in and customizing your settings for a crisper clearer shot.
We have our ISO set at 50 (if you are shaky - use ISO 100)
Superfine mode
Vivid mode
Larger the picture size (2048x1536) (more crisp the shot (making it easier to zoom in the photo and crop while maintaining crispness.)
Overall - for price and quality - I'd give it 5 starts out of 5 for sure.
