Cracked the glass part of my screen, is it worth repairing?

I know that these threads exist for other phones and such but couldn't find one for my s3 that fits the current timeline. I dropped my phone from my pocket while walking and only cracked the glass part of the screen. Touchscreen works fine, there aren't any damages done to the actual screen part, I believe only the gorilla glass is cracked. Service wants 0-0 to repair it but judging by the current phones that are out there is it worth repairing it? I could sell the phone for the parts at around 0-0 and add up money to buy something like a Z2. What are your thoughts about this?
