I thought I would pass along that you can view your trail camera photos in the field with a sony psp. I know a lot of hunters who have children that already own one of these. You can buy a SD adapter to fit the psp. That way you can view it in the field. It runs for about $25 (adapter). Why buy an expensive viewer when you can use one of your children's gaming devices, that you may already have. A psp, if you don't have one runs for about $150-200. At least you can play games on it, when your not using it for photo viewing.
