I sold my 580, so this doesn't really suit my needs anymore and it rarely gets used.. I've used it only a handful of times since getting it last fall, so its in great shape.
Here is the
B&H listing for it:

Looks like going price after rebate is $139 .. I'll sell this one for $115 plus shipping if you don't want to pick it up.
Its a good little softbox.. lights headshots nicely in the field... it just doesn't fit the style (or flash head) I'm using anymore.
The Canon and Nikon flashes both fith nicely in it.. its the Vivitar 285 that doesn't.
