does anywhere from 40 - 150 Hz
Sitting pretty right now at 1280x1024 @ 120 Hz, very very sweet monitor, set me back £350 about 2 years ago, 21", 0.21 dot pitch, flat screen CRT.
Traditional grey and purple sun colours too, the tube is made by Sony, and their version, with the same tube and specs in a different casing slots in over a grand.
If you live in the UK, i could hook you up with one, they're down to £280 now.
