NKNY, I think I've seen them for cheaper. Try pricewatch.com or ecost.com (where I remembered it was cheaper).
Uptick2K, when you look at monitors at the store, it really depends on how they are connected. Usually, the shop will use one computer with a 5-10 multiple analog spliter to display the same images to all those screens. Using that method, any screen will look crapy. You won't see how they actually can perform. Your video card will have an effect on how good your LCD's will look, if you're using analog. Not an issue with digital connections.
Cartm, you can rotate any screen 180 degree provided they have accessable screws to unscrew (4 screws with Vesa mounts). All you need to do is manually unscrew, rotate 180, and screw it back to the base. If you get screens that can rotate, you can still do 90 degree. I have a Viewsonic 191 that can only rotate 90 counterclockwise. I had to unscrew do the 180, screw it back on, and manually rotate the screen clockwise. (yes you can do the rotate by software clockwise or counter, but the viewsonic had one side of the bezel that was fatter than the other).
Having said all that, don't know about the Corneo, they do have good pricing. Excellent price on their plasma as well. Personally I have the viewsonic 191 and Samsung 191T. Samsung hands down (unless you use it for graphics, since when running digitally, you cannot hardware control contrast, temp, or color. Only brightness)
