I'll add my name to the list of those who sacrificed a brave sheet of overhead projector acetate in the name of screen protection... a slightly-too-big rectangle with snips off each corner to ease installation (which was still a bit of a battle). But now--clear, clean, cheap, and zero exposed screen (getting it OFF is a bit of a bother, I discovered, but it's doable if your fingertips are clean and slightly damp so they "grab" the acetate).
Good stuff.
