Dunno about the full monitors, but I've got one of the 25" chassis, and it looks great on a tube/yolk from a 7000 series WG, (Except it has a blooming problem)
I had it installed with a 25" from a thompson tv (RCA) and had a soft focus problem with that tube. (No keystoning, etc) it's just when you would focus the center of the screen the edges would be blurry or vice versa.
I would use these to replace location game chassis, but for us picky bas*(&*^ at home, you might want to consider a real monitor.
Yes they work, but the quality is what you would expect from a budget part.
