Snagged a pair of 21" Trinitron monitors with some minor problems for a fire sale price. I set up one as a second monitor to complement my 19" Trinitron. Now, I fear for the collapse of my desk and the resulting loss of my legs. Meanwhile, however, I have lots of room for spreadsheets and such. And hey, no extra room lighting needed.
This thing has a few quirks that will keep it from becoming my primary monitor, but man, when it's working right, it's a gorgeous display. And 1600x1200 is... liberating. I had thought I might go the LCD route for my next display upgrade, but now I'm thinking I may stick with this config or go buy a 21" Trinitron that actually works right. Or two.
