I still haven't put a Glass protector on mine yet (even though I have been meaning to for months now ) so I guess you can take my suggestion with a grain of salt...
But when I was researching them all, the thing that I kept running into was some people that were using them from various manufacturers were finding that the screen protectors that covered the front facing camera sometimes caused interference. Rainbow effects and sometimes even a bit skewing under different lighting conditions.

That being said,
I found that Mime offers a Feather Glass that doesn't cover the front lens.
Their original style Ghost Glass (which is thicker) does cover the lens, but when I talked to them directly they said if I wanted the Ghost Glass they would be happy to cut me one in the Feather Glass Style at no additional charge. For that reason, Mime's good track record with customer service, and price point, they will be my pick when I finally purchase a Glass Screen Protector.
Hope this helps.

 

Might I suggest Seidio's Vitreo screen protector? I MUCH prefer it to the (2) glas.tr that I had.

 

Zagg is highly recommended

 

I second Zagg Invisible Shield.

 

I'd be interested to see how you get on with it. I hate the plastic screen protectors, they feel horrid but I've been put off the glass ones because they are strictly one shot and if you cock it up, you have to buy a new one.

Let us know how easy it was to apply and whether you managed to avoid getting any dust under it.

 

Assuming that every company is using the gorilla glass, which my HTC Thunderbolt had, in over 2.5 years of daily use without any protection at all for over 95% of the time, it has one little scratch on it. Unless you are in a dirty environment where your hands get sand or abrasives on them often, you probably are being overprotective. The phone isn't an heirloom, you'll have it for two years or so, and then shitcan it.

 

I put one of these on my S4 and I'm very happy with it. For me, installation was easier than polymer protecters. I have two small dust specs but they are smaller than what I usually end up with.
