My new off-camera lighting system.
1* Impact Umbrella Kit, from B&H (Includes the light stands, flash holder, umbrella which has a removable black part) ($100)
2* Vivitar 285HV ($80 each, new)
2* Cactus V2s Radio Receiver. I got the kit and a spare receiver. ($50 for the whole set of 2 receivers and 1 transmitter)
This works pretty well, and costs about $320 in total. I had one Vivitar 285HV from before.
The main thing here that is low quality is the wireless radio triggers, the next step up is a set of PocketWizard II Plus, but that is $180 each, and I would need 3 here.
I also added an antenna to the Cactus flash transmitter, using these instructions
