I don't think I'd get any of those ... see them in person yourself to decide though.
The best LCD roundup I've found have been those on tomshardware.com ...
I'd probably go for a Samsung 171T or 171S or something myself, or if you know of a rebranded LCD that uses one of the Samsung panels for cheaper that might be a good way to go, too (I heard that perhaps some of Dell's FP series use Samsung?)
