My Iiyama S900MT1 is a 19" CRT monitor, which I use to do 1280x1024 @ 85Hz (it can do higher, but not at that refresh rate) , is a few years old now, and no degradation in image output. It's a very nice monitor, and it is cheap. I got mine for £180 from Dabs.
I've had very good experiences with Iiyama monitors and Iiyama tech support (when old monitors need maintenance), I whole-heartedly recommend them.
An example of the good support is with a 17" monitor that was out of guarantee. Iiyama paid for P&P both ways and no cost for the maintenance to tweak the slightly scewed display. Nice attitude as well.
The other thing I should mention is that refresh rates < 72Hz are very bad for your eyes and brain.
