I'm using a 2443BW here at work, and it's a pretty great panel, especially considering it's listing for like $350 now. I think that the 2443BW and the T240HD use the same panel, but the matte black casing and HAS make it a bit more appealing in my eyes. I bought a Dell 2408WFP a while ago, and have been drooling all over it ever since, but you'll also end up paying quite a premium for it over just another TN panel. It's a PVA panel as well, so it might just be worth it to get the Philips IPS if you can get a better deal on it.
One site that I can really recommend for monitor comparisons is
DigitalVersus, which is affiliated with Tom's Hardware in some way. They have a reasonable amount of data for monitors, and they make it easy to compare specs side by side to help you make a decision.
