Just a heads up, I really like the iDC Triplethreat flash bracket. I wanted to get another couple (I keep losing them!) and emailed iDC, I pointed out that at $59 they were well above the price of the Bruce Dorn version available for pre-order from B&H, I made them an offer of $100 for three.
They just emailed me back saying they are selling their last remaining stock for $33.99 each, then they are done. I ordered three, I just need to stop losing them now!http://www.idcphotovideo.com/store/triple-threat-traditional
EDIT: I forgot to add why I prefer them to other designs, I love that they are evenly spaced around the modifier shaft, I can use two on one shaft for six lights (I have five 550EX's and three 600EX-RT's) but best of all, they don't have clamp coldshoes, the slots work much better for the lever style Canon strobes. Great $35 worth.
