U should also consider SONY,,,i hav a sony DSC-P41 4.1 megapixel camera.
i dont hav any problem till now,, ive been using original sony rechargeable batteries from the last one year with no hassles.......
just keep one thing in mind..while buying a digital camera, its obvious that people
look for high megapixel count,,,, a 5 megapixel camera will be fine for your needs.... but the main thing is the sensor.. go for Cameras having a CCD sensor.
On the other hand, CMOS cameras will be energy-efficient but will not give as
much clarity as the CCD ones!!!!...
after u hav a choice of 4-3 models from different makes,,, goto
www.dpreview.com to get a review of those models,,,the site also has a collection of images shot by every camera, to give u an idea about everything...
