[pct-l] any portable solar panel recommendations?

[phix at optigan.com (Pea Hicks)]

hi all-

does anyone out there have any experience using any of the portable 
solar power units for recharging batteries, etc, while hiking? any 
recommendations in terms of light weight and decent charging 
time/ability? i'm doing the jmt in sept. and i mostly need it for my 
mini-dv cam, whose batteries are far too expensive to simply carry 
several extras. ideally it'd be nice to have something that i can attach 
to my pack in such a way that i can charge up while hiking. looks like 
the Brunton SolarRoll is pretty cool, though pricey.

thanks in advance!
