Need a new Camera... HELP

I need a new digital camera.  First it has to take good photos in light and dark w/flash.  Next battery is a concern.  My current camera has it's own rechargeable battery, which I only charge 3 times a year.  And I take roughly 2 to 3  thousand pictures a year. I want that again.  I have seen my friends on vacation changing batteries 2 or 3 times a day.  I don't want that, I can't believe how some cameras eat batteries.  What is the best camera??  Review your camera for me!
