I would like to suggest staying away from ebay and trying bhphotovideo.com
There is a used section there, and they are pretty good about rating the wear and tear on a turned in camera.
In fact, you might want to step HALFWAY from digital point and shoot to DSLR and dally a bit in the bridge lines
that ease you into the heavy gear and might be your last stop, or might be a learning camera for the next step.

I have the last one, bought at B&H used. Shoots great photos AND 1080 HD video, has a great zoom range and while
it is not a DSLR, I think you will enjoy it as a bridge and might never sell it simply for the HD video.

That's my Flickr page, I used both of my canon bridge cameras to shoot the various photos on it, though.
I also have the cheaper, less feature packed, but ironically higher-regarded S5 IS from Canon.
