I've put together a search engine that uses Google to search for camera equipment. It's called www.gearsearch.info
It lets you search flickriver for photos made with a camera, film, software, or anything photographic to get an idea of what that tool is capable of. You can also access manuals and browse eBay auction with it.

I would love for you to try it out and to hear your feed back.
Thanks in advance,
John
