If you are looking for something very inexpensive, check ebay as someone already mentioned. I have a couple from ebay and they are great for a cheap bag. They are not heavily padded, about 1/4" thick, but provide some protection from knocks. I have the ones that say 'Nikon' with a 'D' underneath. Unauthorized, I'm sure. I don't really care for the labeling and cover it with black tape. They are about $8 or $9 and shipped from China so it takes a couple weeks. I have better bags for when I need protection but these are good around the house or going to my kid's games. They are not too bulky, so you could throw one into a backpack or suitcase if you needed to. They have a removable neck strap, a little top carry handle and two small side pockets. Belt loop too, but that would be kind of awkward.
