My main screen is a good monitor, but for my other two I got lucky with Circuitcity selling off the last of their cheap little 17" Hanns¯¯•G screens... These: http://www.newegg.com/Product/Produc...82E16824254018 got one for 140? and the display 30% off that...

I'm loving them turned 90 degrees.

If you don't mind the heat or power consumption (which it sounds like you do, you know, specifying LCD) you can pick up some nice 17-19" CRTs rediculously cheap (I picked up a really nice Phillips for 25 cents at a local thrift store lol)

For awhile there you could find the one resolution smaller LCDs really cheap... (Pretty sure they're native 1024x768, but I'm not certain) but now you just can't find them at all :P
