My wife has broken a second D-490z and I'd like to move up to a Minolta a1. Any reason I should not buy her one of the c-720s going on ebay right now of $100.00. All we'll do with it is take shots of the kids. 3 mp seems fine for max 8x10 enlargements. I like the idea of the 8x zoom because it seems that if you get close enough to kids to get a good candid shot they react to the camera and ruin the shot. Also, I still have a couple smart media cards from the 490 that I'd like to not just throw away. Anybody disagree with my reasoning or aware of any problems with the 720?
