u don't really have a choice at that price point unless you wait for the u2410 to go on sale, which is usually $100 more than the u2412. The next price bracket up goes to $500+tax. Then you can look at the NEC, HP, and the Asus.
look on
TFTCentral and shopbot.ca the models that interest you. i thought about lining up @ NCIX's grand opening to grab the LG 23" IPS for $179 but was too lazy. I have a Spyder coming so I'll wait for the next DoD or Ultrasharp to go on sale.
Is 24" that much bigger? I'm using a 23" @ 2048x1152 about 3.5ft away from me and I think it's decent. I understand that bigger is probably better ...
