I don't think I've had the pleasure of welcoming you to Shuttertalk. So, welcome! Anyway, can't help much on the sigma. I have the 420ex.

Hi Clengster
I've got a Sigma EF-500 DG super,
I haven't experienced many other flashes - although a slight playing around with my friend's Canon 550EX, but just from feeling the 550EX, it feels more solid.
I guess they both do the same thing, but reading from comparisons between the two, I think some differences include: custom functions are available on the 550EX and not on the Sigma and that the Sigma only uses the centre focus point area for metering whereas the 550EX uses whichever is selected?

Check out this page:

but I'm not sure between the similarities between the ST and the SUPER.

and welcome!!!!

I had the Sigma 500 DG Super flash in the past and used it with my old Minolta Dimage 7i camera. This flash had wireless capabilities and a very nice set of controls and features - so I guess I was pretty much happy with it. On paper the Sigma is almost identical to the "original" flashes from Canon, Nikon, Minolta, Olympus etc - but it also has lower build quality, lower power output in most cases and may lack a feature or two from the "original" flash.
