I'm looking at the wireless on the Midwest Photo Exchange with the vivitar 285hv and the cheapy cactus wireless set along with the stands and cameras. Curtis N was trying to convince me to pick up the Sigma 530. I was looking at possibly getting the sigma, the wireless transmitter and receiver and seeing if I can still swing the umbrella and stuff.
How necessary is the umbrella and stand?
Any personal reccomendations? The pocket wizards are a little out of my league right now and I've looked up an antenna mod that a few people that tried that seem to increase the range and reliability of the cheapy set.
