I carry mine in a Tamrac 5689. This was the smallest quality bag that I could find that gives good protection, and also the camera slides in without any force needed- some bags are too tight a fit. A spare battery will fit in the bottom under the camera, I wrap it in a little padding to stop any abrasion. Also a small pouch which is under the flap when fastened will take spare cards. I think I paid @ £15 on Amazon.
