I needed a diffuser for my pop-up flash and picked up a "Puffer" which is made by Gary Fong. Although it isn't as nice as a seperate flash with a soft box of some short I was very impressed with the results. It actually makes the built in flash usable. It gets rid of the harsh spots on bald heads and smooth skin and you don't get harsh shadows behind the subjects. For $20, it's a no brainer if you ever want to shoot w/o an external flash.
