I was considering the CyberSync transmitter and receivers ... until I read this review:

That one review points out enough major problems that I came to the conclusion that if you want radio triggers you should either buy the super-cheap Chinese (Cactus) triggers or save your money and buy PocketWizards.
If you're not a working photographer and you can tolerate several misfires when using the cheap ebay triggers then get the cheap ebay triggers. If you're a working photographer who depends on the consistency of wireless flash there still isn't a GOOD and RELIABLE "cheap" alternative to PocketWizards.
