Frankly, we're much more interested in the DIY Ring Flash, which promises to convert your normal sized strobe into a ring flash for just $24.95. They've tested it with a handful of units (Nikon SB28, SB80dx, SB800, SB26; Canon 430EX, 580EXII; and Vivitar 285) but it should work with most models. It ships as a perfectly flat set, and requires a fair bit of papercraft-like assembly to put together. It has a black matte outer, and a silver reflective ring to do the heavy lifting. At that price, you really can't complain, though it's an extra $8 if you want a bracket mount to go with it. I'm sure gaffer tape will work just fine.
