The DSLR route will cost you money and time learning about photography. If you want to get a camera with an articulating screen and do better than your A630 then you'll have to look at the Canon G11.
I'm in need of some camera advice. I own a Canon PowerShot A630 which I dropped and ruined the LCD screen. I can either have it repaired for about $90.00 or purchase a new camera. What are some suggestions that are either comparable to this one or a slight upgrade. My one complaint about the A630 was that it didn't take good pictures in low light when you couldn't use a flash. I understand in order to accomplish that I may need to upgrade to a SLR digital camera. I'll take suggestions on that too. Any advice you give will be greatly appreciated.
