Have you actually tried the OptiClear monitors? I also demonized them until I used one for several hours. Very crisp, nice, CRT-like picture and the mirror effect is not an issue unless you really play dark games in a brightly lit room or have a light source behind you.
The currently available 19" NECs are:
- 90GX2: OptiClear but clearly the fastest NEC, very good image quality despite TN panel, decent viewing angles as well;
- 1980FXi and 1990SXi: non-glossy and great viewing angles/colors (IPS) but slow... - not recommended for gaming;
- 92XM and 92VM: entry level TN panels - slowish for TN, IMO crappy design, color depth lower than the others, image quality in general not on par with the GX2 series.
As you can see, you don't have much of a choice.
My suggestion: try the 90GX2 and if you really don't like the glossy panel (I think you'll keep it), go for a different brand, like ViewSonic or Samsung. Even though you only indicated relatively slow games, I wouldn't recommend the pricy and slow IPS panels or the entry level TNs with some serious ghosting and subpar IQ.
