Can anybody suggest a nice, hopefully cheap way to get my 580EX off-camera to my 30D?
I'd ideally like it wireless, but guessing that's going to be much more expensive.
Any and all solutions welcome however....

Thanks alot peeps!

not sure what too expensive is. The ST-E2, the proprietary wireless (IR) system from canon costs you £80.
The cheapo wireless systems on the ebay costs even less (like £20 for a emitter and receiver).
a wire and an adapter must cost even less.

Wow, that was fast! Thanks very much.
How would the device in the first ebay link work?
Connect that to the speedlight and then how is it triggered? By the incamera flash?
The ST-E2 sounds like the proper tool for the job but it's just too expensive i think, could only find it for around £120 on Amazon.

*Edit* On a side note; will the Canon Remote Controller RC-1 work with a 30D?

Just a note. I got one of the second options there for a friend and it didn't work. I haven't actually spent the time to figure out why, but I did do a little bit of closer looking and could not get the wireless transmitter to communicate with the receiver under any combination of channels. I'll have to look a bit closer later. I tried with three separate 500 DG super units and another flash that I have. The transmitter was alternately on a 300D and a 30D, and was fired manually with the contacts.

Buy from a brick and mortar store if possible.

Additionally, the flash will become manual if you use it like that. Using RF signals is not compatible with E-TTL with Canon stuff. The 580's and Sigma 500 supers use IR and do allow E-TTL communication off-body.

Google turned up this one.

Note that using manual settings for your flash and/or body, either on-camera or off-camera generally defeats pre-flashes (which often confuse optical slave units badly). Consult your manual for more details.

I like to use cheaper flashes off-body with such systems. Optical slaves are pretty useful in some situations where IR doesn't work well due to line-of-sight issues since optical slaves detect sudden changes in light.
