Why get screen protectors at all? I keep my Droid x in a holster with the screen facing inward. That's the best protection of all. Now if the screen does get a scratch, say from my finger nails, I can always use some plastic polish on it to remove the scratches. So far, there haven't been any.
Any screen protector I have seen doesn't compare to the naked screen. In most cases you can see the protector and it takes something away from the sharp clear images you otherwise see with the naked screen.
