My old trusty 21" CRT (Nokia 445Xi) is having some problems lately, so I'm looking for a new monitor. This monitor will be used almost exclusively for gaming purposes. I'm looking for something in the 20-22" range, since i'll want to play on native resolution, and >24" monitors have huge resolutions, which in turn require very powerfull video cards 
My budget would be a maximum of about 500€
I now own two TN monitors: the one on my laptop (14"), and the one at work (17"), both from Dell. I don't have too many problems with viewing angles, but that's probably due to their small size. I've seen some 22" TN panels that had nasty looking color problems because of their viewing angles, and I really don't want that. That's why I thought I'd go for a non-TN panel, altough these seem hard to find.
I found:
Eizo Flexscan S2231W
NEC MultiSync 20WGX²Pro (has a glossy surface, which I'd rather avoid :p)
(both seem hard to get in Belgium...)
Now, my question is two-fold: is it worth going for a non-TN panel, since I'll just use it for gaming, and are there any other (non-TN) monitors around that are suitable for gaming ?
