So, I ordered the Cactus PT-04 wireless flash release (offered by Gadget Infinity, out of Hong Kong). I bought mine off their E-Bay store, and am awaiting them eagerly. With a range of 30 meters, they should do well until such time that I feel that Pocket Wizards are appropriate. Right now, several hundred dollars is too much.
I ordered a transmitter and two receivers, which set me back $58.90 with shipping. That’s pretty reasonable. I’ll post an in-depth review when I get them in my hands.
