and I want one
pretty much agree...
though photozone says 21 is all in all probably better and only loses 1/3 of stop and is even smaller... but I haven't bought it yet either.
anyway, 20/2.8 is really rare (not that 24* would be common or what)
so good luck,
you'll need it
as far as rendering of Sigma 24/2.8 goes, I'm pretty happy... The two closes lenses I have, to compare it to are 10-20 which gets beaten by quite a margin (at 20mm) and FA31.... well I don't even dare to do comparison shoot, simply lost time.
But generaly 24 is fine
