NCIX has 24"s every week. However, today is Dell's last day, on their Days of Deals specials, and they have a 24" for a good discount. It's not the Ultra (IPS), but it's still good:
DELL Dell - Professional P2412H 24-inch Widescreen Flat Panel Monitor with LED : Computer Components | Dell Canada
Shipping is free. Unless you want something tomorrow, then I'd go for this deal.
