OK so my ten year old 420EX finally died
time to replace it then 
I was just going to rush out and buy a 430EXII as a more modern replacement but thought I would check in on other options with you guys first.
First up, only only ever use the flash on camera when I am out and about, mainly as a bounce flash, so I don't want anything too heavy or bulky.
Second up, I have a full four strobe studio flash setup, so I doubt I will do the whole multiple speed-lite wireless thing.
So is it worth looking at the 580EXII or is that money better spent on a wide angle lens which is also on my to do list
