I bought it off of eBay. It was called a E-510 Starter kit, and came with the bag, a Hoya Filter (58mm) and some other small accessories. I loaded it up with my u4/3 gear and I think it's perfect for that.
I don't use it anymore, though, as I've got too many lenses and I wanted something that was a bit more discreet. If you are seriously interested, PM me and we'll see if we can figure out a suitable price.
