either a set of ebay triggers or a cord. Using a cord will allow you to retain ttl metering, the wireless triggers mean using the flash in manual....


:bonk:From personal experience the cheap triggers do not work well with the 430ex or 580 ex no matter what the claims on ebay. I have tried three lots and none consitantly work. I would go with a cable, a canon ste2 or bite the bullet and get pocket wizards.
