I use the LowePro Slingshot 202 and absolutely love it - it has a great ergonomic padded strap, plenty of room for DSLR camera with a couple of lenses plus flash and all the extra filters, batteries/memory cards, etc. It swings around to the front of your body where you can access your camera quickly, and you can even rest your camera on the case for stability while taking photos. I highly recommend LowePro - they come in several different sizes. I think the may have actually added some features/improvemets since I bought mine several years ago.
