can you recommend a light digital camera for cycle-touring?

Seeking recommendations on a compact digital camera for long-distance
self-contained bike tours. My criteria are: decent zoom range (4X would
be ideal), decent flash range, easy to grip, size and weight, battery
life (capabability with CR-VS batteries), a few "options" such as black
and white/sepia and landscape, and of course, overall quality.
Particularly interested in any experience with Nikon Coolpix L-3, Sony
Cybershot-DSC-W5 or P150, Canon Powershot A520, Olympus D-580 Zoom. I
have a Fuji 500 that's light and good to grip but has crappy with flash
range, controls hard to manipulate and has a lot interval between
shots. I'm not overall concerned with number of megapixels. Thanks.
Phil
