I have been searching all the backpacks I can find but I don't want to spend $150 and up for one. I just customized a Seahorse Case which is great, but I just wasn't thinking. I live in an area where having a backpack makes more sense. The Seahorse is great for traveling and storing, but not so much if you have to go up a trail. A camera backpack has plenty of adjustable dividers, but it has to be able to accommodate the height of the bird. Has anyone else customized an inexpensive camera backpack for the P3? I was thinking about trying this one, http://goo.gl/GuxsvY, becuase one review did customize it, but Amazon is probably about ready to revoke my Prime Membership if I return anything else.
