Greetings! I was thinking of getting a new cheap flash as a slave that is as good (or preferably better) than my Canon 580 EX II. Since there's many out there (and I don't know how to ready guide numbers properly), could anyone recommend me a good cheaper slave flash? I was thinking of grabbing another 580 EX II.





First requirement is that it could be triggered by IR (since PW comes later). I was checking a third part lens, Nissin and they have the Di-866 http://www.nissindigital.com/en/Di866-1.html. It's about 200 USD cheaper than Canon's. Any other alternatives?
