I've got 184 passwords tracked by pwsafe. Because I use MS Windows so rarely, my password database tracked by Password Safe is much more modest -- about a dozen.
KeePass does look like a decent application, but my calling my experience with it "limited" would be pretty generous, so I can't really comment on it much. My biggest concern would be design complexity and compatibility with the tools I use on Unix-like systems. The KeePass interface is not in the least designed to work well with the kind of workflow I use, so compatibility with other tools becomes kind of important; I need nothing more than a command line interface and keyboard shortcuts on Unix-like systems, and the rest just gets in the way, so KeePass would not qualify to be my tool of choice.
