The Last Strobist Standing
Coming away from that, I discovered that we have an all-in-one kit for active hobbyists who have at least one speed light and the desire to modify the output. You get attachment accessories that let you put on a snoot, diffuser, grids, filters, or small softbox. The filter holder bears a slight resemblance to the ones made by C---n or L-- but is sized for 3 1/2 inch filters and good luck finding those.
The rest of the gear is pretty useful, and as it is all in one set you can get a good variety of looks going and experiment. If you've got a speed light setup that runs to several heads it is perfect for portable portraiture.
Pardon the terrible pack shots but it is too big to fit in the editorial light tent.
