If you want a cheap Trinitron, check out KDS. (www.kdsusa.com) The AV-195TF 19" can be found online for about $400 + 45 shipping. A complete steal for the price. 1600x1200@85hz, 18" viewable, FD Trinitron tube. A Sony or Mitsubishi branded version of the same monitor would cost over $600.
The AV7TF 17" version is similarly cheap for what you get at $224 + shipping. Unfortunately it only does 1280x1024@60hz, so unless you want a headache you'll have to stick with 1024x768. They discontinued the AV9T which has a standard Trinitron tube but does 1600x1200@75hz or 1280x1024@85hz.
I know 6 or 7 people all with KDS monitors (at least 2 of them are 195TF's) and they all really like them. They also come with a 3 year warranty from KDS. They're a complete steal if you ask me.
