I feel you may have been burnt on previous TN's Boom but I did pay £500 for my Asus VG278H monitor (which is TN) and running SBS with a £500 Dell IPS, the image quality is damned good. IPS for me is better at deep colours and blacks look black but for everyday gaming, I still use the Asus TN panel. If I get low to the ground, the TN looks rubbish, while the Dell still holds its clarity but I don't tend to game laying on the floor (Might have done a few times when drunk but can't remember, so doesn't count

).
TN has certainly moved on and PCM2 is the man to explain why (the monitor section man is a legend). I certainly have no issues buying another TN but if it is muck, I will let you know.
Damned waiting game is gonna kill me
