I have a small Sony 10.1 megapixel camera, and its more than I need currently. It sells under 300.00 and uses the memory cards compatible with all other Sony products. I would probably get the DSC-W300 today and upgrade to 13.6 megapixels.
Anything from canon i would suggest.I have both the A540 which is like 5 years old but it still takes great pictures and i have the S3IS.for a 6mp camera it takes great close ups and also has 12x optical zoom.u can find them on ebay for around 250.
