I would look at the Fuji F100fd instead of the Z series. Here is a video of the Z100fd that was pretty decent.

The Panasonic is a little bit slow for my taste.

The Sony DSC-200 is a pretty good camera for what your asking for. The Canon SD series are very good also, but they're 4x zoom compared to the others 5x zooms.
