I had a KDS 19 inch FD Trinitron for a while.
They are very nicely priced and the image quality was up to par with any other FD Trinitron I've seen (that is to say it was really nice), but I had to exchange it 3 times in an 18 month period as it went belly up prematurely.
They seem to be good monitors, but I have heard and expereinced that they're return rates can be kinda high due to poor quality control. Just gotta be lucky and get a good one, or be willing to exhange it a couple times. Just my experience though - hope it helps.
