My 520 just arrived and its packed in a cardboard box with a molded insert. In my "Googling" I have not found a backpack or case made specifically for it. Anybody else have any luck with a case? I know the promotional video showed a back pack where the 520 was strapped to the outside, but I haven't seen that anywhere. The molded insert would be nice as an insert into a Pelican case, but the dimensions don't match up with any as far as I can tell. Suggestions?
