I just purchased the 430 and I am very happy with it.It does a great job for what i use it for. I am actually not a fan a using a flash but there are times when you need it. I could havespent the money forthe 580 but i just felt for the limited amount of use the flash is going to get (let alone using multiple flashes) it just wasn't worth it for me. I am not a studio photographer so multipleflash unitswere reallynot thatexciting to me.


Ithink it really dependson what your usage is going to be.
