DV2, ghosting isn't that bad on an IPS unless your talking about circa 2003 panels. Yes there is a tiny bit of blur, but it's maybe 1/10th the blur of the standard in-game motion blur effect I've seen in Crysis, The Witcher 2, or Just Cause 2.
As for input lag, give credit were it's due many of the panels with the lowest lag are IPS panels. The u2312hm, an IPS panel, is even competitive against CRTs.
Giants84, Dell's ultrasharp line is high quality, same as their alienware line. Though, I won't vouch for the rest of their monitors.
I have an Alienware OptX AW2310 it's in storage, the colors looked like they were in sepia tone.
HP uses too much AR coating.
Samsung has an awful IPS stand in they call PLS, and they charge too much for TN.
NEC costs too much, and has too much input lag.
Apple is going thunderbolt, so good luck getting it to work on a PC
Asus is okay, they are just getting into IPS, their upcoming 27" panel might be good.
