I never got headaches from mine at a responsible refresh rate.
Sun GDM-5410. Bought it from my local college's scrap shop for $65. Replaced a 19" Viewsonic VX910 LCD which cost (at the time) 350 dollars. 1600x1200 at 85Hz looked great.
I used it til 2007, sold it to a co-worker for $25. Replaced it with a Samsung 20" TN LCD which lasted about 3 months before I abandoned it, after earning a big bonus, for a 24" Soyo with a PVA panel. Even still, I dislike that I have to swing the monitor for the best picture, and I can't do 2048x1536 even if solely for the lulz.
