I got it from zagg.com. Some of the best, if you ask me.
Figured since the Sony505 used the same e-Ink screen it would fit.
And it did, perfectly. But compare to the "dull/non reflective" surface on the screen, the protector did add some annoying glare to the screen.
So after 1 month I removed it.. But still way better then the on included. So if you are not reading in direct sunlight..
Here you go..
