I have some Amazon gift certificates, about $500 worth. What should I get?


I have 580II and 420 Speedlights. 5DmII, 16-35mm and 24-105mm, B+W circular polarizers for said lenses, Gitzo tripod and head, and various Lowepro bags.


I'm waiting on another lens until the new 70-200 comes out. I want to upgrade my ball head to a RRS, but later ... I will get LightRoom 3 when it comes out, in the meantime I have money burning a hole in my pocket. Help me spend it!


I'm considering a light meter, but I'm not sure which one, or how much its worth it. Any other suggestions? I do landscapes/nature, and want to get into portraits of the family (so will be learning about strobes, etc)
