I've always used FSScreen, simply because of it's pure simplicity. When it's running, all you have to do is hit the PrtScrn button. That button normally puts a screen image onto the system clipboard, but FSScreen immediately pulls that image back out and makes it into a 24-bit bmp file in the same folder that the app sits in. It doesn't work with any other format, or resize, but that's OK with me because it gives me more control over that stuff. I keep a shortcut to the app right next to the shortcut to FS9.
