Thanks for your input on my camera problem, Dave and Meesha. Since I can get a new Canon SD Powershot for about $100 at Best Buy online and get it sent without any shipping charge, that's probably what I'll do. I couldn't find any source that was cheaper.
There's no sense in my getting a camera with highfalutin' features, because I wouldn't use them. If you look in the dictionary under "point-and-shoot", you'll probably see me mentioned in the description somewhere. I don't like to change settings.
I could most likely get some other kind of point-and-shoot camera cheaper, but I hate change, and this is the third one of these little prizes I've owned. I know it like the back of my hand. I like the way the lithium battery stays charged up for weeks, even with fairly heavy use. I am one person you won't see at some one-time event saying, "Oh darn, the batteries are run down."
I like the way the Powershot fits in a pocket, since it's about the same size as a pack of cigarettes. I like the videos I take with it.
My Powershots have never done me anything but right. The one I had before this one still worked when I retired it, even after I sat on it; the viewfinder was busted, but the camera took pictures just fine.
