Personally, I'd go with the LG Flatron 915FT Plus. It's a great unit. I don't know much about the others aside from the NEC which I did try. It was alright, but the two aperature grille lines (which the LG monitor does *not* have) annoyed me and I just could not get used to them. I think that's something that depends on the person though - some people are probably fine with them. (The model I tried also seemed to shut off and turn back on randomly, but that could have been an unsecure power plug or video cable - not sure, and it wasn't a major problem). I've been using the LG for a little while and have been quite pleased.
I'd go with the LG Flatron 915FT Plus too. Overall its a great monitor. I like the anti-glare and anti-static coatings. The images are bright and sharp. It has an USB hub at the back and the monitor meets TCO'99 requirements.
