Hmmm. well just to add another data point, I got my grade B from the computer cables & cases company or whatever they were called and it's pretty nice too! Physically I had to look very closely to see that the top had a hint of discoloration (a lot less than my 19" it's replacing!) and some very subtle "stripes" on the top that I suspect might be related to heat coming through some of the EMC shielding or something. Operationally, the colors are fantastic!
I'm not completely sure about the fact that it looked like it had some squiggles on-screen when drawing a constant color background (the kind of stuff that degaussing seemed like it oughta fix!), but I haven't noticed it while using the monitor. It also seems like the whites flicker or something, even with the refresh rate up at 85 Hz. I'm convinced I really am at 85Hz, but keep worrying a little that the on screen display always shows 60Hz. Odd.
I'm sure, though, that we'll have a long happy life together! lol
