I wanted the "paper feel", which gives the screen a bit of roughness so it feels like writing on paper rather than glass. I went with this brand on Amazon and have been very happy with it:

I bought it 18 months ago and still haven't needed to replace it. I can clean it as easily as the bare screen.
These types of layers add a very tiny amount of color distortion, so I guess not recommended if you do professional graphics work on the thing.
