http://www.pacdesigns.com/ $350 is worth it if you get a bag that, for most people, will last a REALLY long time. and you get some custom options. i don't think the solar bag is either of those.

i think someone made the same arguement about custom frames (why spend so much when you can get almost the same thing cheaper). yeah, it's expensive, but you get what you pay for.

but in the end, i sure wouldn't pay 350 just because the bag has a solar panel on it. i have a feeling it wouldn't last as long as even a cheap messenger bag.
