Digital Camera

I'm had plans of buying a digital camera. So I was doing some reading on what to look for in the cameras. With new models coming out every other day, I posted my needs in bulletin board so that folks having knowledge about cameras would help me in finding one which suits me. I got quick replies and there a guy named visu who explain the different things that I should look in the digital cameras and some of my queries. Another guy suggested Cannon Powershot A540 as a good pick. Still searching for models in Cannon/Olympus which will fit in my budget and needs
