I was psyched when I bought my first Lightscribe drive, but I ended up only using it once. It's easier and faster for me to just use a marker =/ .
My result with the one disc that I tried was mixed: the image was excellent, but the contrast is pretty poor. It is very difficult to see, so I ended up using a marker on that one too, ha. I think I could have gotten some better results with different settings & different-colored discs though, so the mediocre results were really my fault.
If you sell your own music or programs, or just like a little flare on your discs, it can certainly do what you need. The technology works, no doubt.
