Hi A.,
We got my grandma a camera last year, I don't remember the brand, I think it was a canon. My grandma requested that the camera had a window to look through with your eye and not just the screen because sometimes there is a glare on screen that make it difficult to see. Also that the buttons are large enough for her to use (a lot of cameras are pretty small) and the fewer buttons the better. Ease of use is extremely important. Ask a salesman at a camera store where you can try the cameras, such as Best Buy, and then shop around for the cheapest price once you know what you want. Not all stores have the cameras hooked up to a power source so you are unable to see how easy or difficult they are to use.
Hope that helps!
