I own a few sunbounce reflectors. But only the big ones. While they are good, they are a bit difficult to carry around when travelling with small gear. So I was looking for something else to have with me on indoor shoots. A reflector of a medium size (tending more towards small), light-weight and one that can be used without an assistant around.
I checked the options at my local dealer GM Foto and bought the Lastolite Sunfire/White, 20 inch one. It is super small when folded, pops up automatically and was so much more inexpensive than the others, that I decided for this one.
