Sorry you haven't gotten a responce. I think the Tamrac Velocity 7 or 9 would do nicely. It is a sling bag that top loads and will have enough space to add a flash and a few other small items. As far as a strict toploader Lowpro makes a few good ones so does Tamrac.
My suggestion is when you get your D50 go to the store and try a few because bags are very personal things and you need to see how they feel with the camera in them and how they carry for you. Kind Regards Jim

The problem I have with toploaders is simply that they look like camera cases. "Hey, I've got an expensive camera inside - steal me!" I can see that they are useful in some types of photography but for general use I think eiher satchels or backpacks blend in better. My personal preference is Crumpler but a good place to start looking for an overview is www.cambags.com
