I'm buying a digital camera since i don't have one. I've never owned a digital camera and I don't know ****** about them but I've done enough research to know what the good brands are. I'm looking at the Canon A530 and A540. Ritz Camera has the A530 for $115 w/free shipping after Google checkout. The A540 will probably run around $180 (from new egg). Which one should i go for? Am i getting that much more with the A540 and Is it worth the extra 60 bucks?
