I have seen the Goal Zero in a local shop, but never used them. They seem really well built. The biggest difference I see is the Goal Zero panels are not flexible. I am too rough with my stuff to trust something that can crack.

If I were to pick up any Goal Zero products, it would be the Guide 10 Plus Adventure Kit. I don't want another battery to lug around, and the Guide 10 lets you just charge the batteries you already use - Assuming your electronics are all AA and AAA batteries like mine.
