My used $50 Glo came today and it really is in pristine condition, no flaws at all (once I wiped finger smudges off it of course
). That I had to wipe those smudges off makes me think they didn't use it much, since mine seem to reach a point where the smudges don't show anymore and pretty quickly.
And this screen with the front light on is also a little whiter than the other two are. I can turn the light output down a bit and still have it look the same as the others.
