I want to purchasing a digital camera because I'm interested in photography. I've been doing some research and am leaning towards something from Canon. I'd like to have at least 7 mega-pixels with optional zoom. I'd like to keep the price-point below $150 and I'd prefer something that could fit into a purse or back pocket. But I've read a lot of different reviews for different camera's and am having a hard time narrowing my search down. Do you have any recommendations for someone who'd like to get her feet wet?
