I just got the screen gurads from Seidio
Ultimate Screen Guard
I love the quality. I can not tell that it is there. The ONLY thing that you must do is make SURE that there is no dust on the screen prior to application. I had a can of compressed air handy during installation to blow off any dust. If you take the time and make sure that you do not touch the side that goes on the handheld and squesse the bubbles VERY carefully using a slightly damp micro-fiber cloth, the guard will NOT be visible.
I installed it on all 3 8900's I got and unless you look at it very closely, you will not know there is a screen guard.
