Very very late on this, but despite the naysayers, I've had pretty
good experience with half a dozen Sigma EX lenses. The 20/1.8 is my
favourite widey for gig shots (have a PDML Book submission taken
with it), and I'd say the 24/1.8 is a tad more useful than the
FA24/2. May just be luck, but in extreme lighting, the Sig 24 is
sharper, has less PP, and focuses slightly closer.
About a month ago, I picked up a Sigma 20/1.8. In most respects, I
really liked the lens. Unfortunately, something about the manual focus
felt very lumpy. I mentioned this problem on the list. I talked with
Sigma, decided that I'd send it in for repair, but after the
holidays. The lens worked, it was just a bit unpleasant to use.
This week I was going to pack it up to ship it off to Sigma. While I
was writing the letter describing the problems, I realized that the
mysterious lumpiness had gone away. I don't know what the problem
was, maybe a lump of grease on one of the gears, but it seems to have
solved itself.
Over all, I'm very happy with the lens. Here's a set that I shot
tonight with it:

Band at ISO 400-640, dancers at 3200, all manual focus, manual
exposure (1/10-1/25 sec at f/1.8)
The focus still feels like a cheap kit lens, but it's reasonably
sharp, and it's fast enough for my uses.
