The Epson 85HD MovieMate works very well for putting up lyrics, and the more I use OpenLP, the more impressed I get. For free software, it is pretty darn impressive. I can see why some people are skipping large screen TVs and using the Epson instead.
UPDATE: One nuisance: the notebook is an older Compaq NC6000, and the drivers that came with it would not do two separate displays--it would only clone the screen to the external SVGA port. Fortunately, even though this is now a several year old notebook, HP had a driver update that supports dual displays.
