I just bought the KDS Rad-7s 17" Ultra-thin LCD for a dual monitor setup under windows xp. It rocks! I have the screen size at 1280x1024 and the text/colors/pictures are so clear, even better than my 21" CRT monitor. I highly recommend it.
The cheapest price is at www.samsclub.com for $499.00. They carry it off and on, currently they only have the KDS 19" LCD for $999.00, but just keep checking back. It's worth it.
