Haaa you can tell you don't know me well - I wouldn't buy my liver - in fact, I could do with a new one myself
The Canon 430EX II does 97% of what the 580 does. Ive got the 430EXII and its fantastic! Also.. buy a yonguno wireless flash trigger, excellent and cheap as chips!
I popped into my local specialist camera shop at the weekend and they had just had a secondhand Canon one in - its not quite the 430EX but nearly - its a 420EX (I know some of you said not to buy secondhand but I do have 12 months guarantee) which leaves me with a bit more money for more equipment so I'm happy Thanks to you all for pointing me in the right direction
Hope you're not going to start showing off in the monthly competition now that you've got a decent flash gun!
Ive got a cheapy Jessops TTL Flashgun. Seems to do the job well enough. On an EOS 500D. http://www.jessops.com/online.store/products/67557/show.html Thats the one.
