I just got a Samsung 930B, which I really thing is the same exact panel as the L90D+ since it has the exact same specs. The only differences are that it is black (a plus), it has a very simple base with no swivel or rotation (a small minus), and no DVI cable included (no difference to me since I had one laying aroud at work that i'll connect today, but to others it matters)
overall the monitor is great, some image issues however I excpect to get fixed once I connect using DVI, I'll post more info after I do so.
The biggest downside to getting this monitor is that I had to pay $473 up front, and I'll be getting a $90 rebate within 2 months. But at the same time, if I find that the image issues (slight moire in text, other stuff like that) don't go away with DVI, I can simply drive over to BestBuy and exchange it for a new one.
EDIT: UPDATE: I connected the DVI cable, and to be honest, I didn't expect this much improvement, text is clear and sharp in both normal and ClearType modes, all other issues seem to be gone too. Overall the picture seems to be sharper. I am very impressed.
