Is Canon Powershot A610 digital camera is good?

Yes, it麓s good.
I don麓t know that camera myself but I do know two websites that always provide fantastic, independent reviews: www.dpreview.com and www.steves-digicams.com
The first site doesn麓t have a full review of the A610, but all the user comments are positive. The second site does have a full review, and they highly recommend the A610. Read the conclusion here:
