The part of the screen you scratched can be replace. If you bought the top half of the phone shell it comes with that plastic screen built into it.

As for quality screen protectors. I'm personally a massive fan of the ones BoxWave sells. They are completely invisible on the screen and hold up insanely well. I've been using them for years now and every phone I've had them on has had a perfect screen its entire life.
