[Q] Glass Broken topic

The touch screen glass of my Nexus 5 is broken but the screen is working absolutely fine. I need to change the glass of the phone but customer care charges me Rs. 8000 (INR) for replacing the whole LCD DIsplay. Should I go buy a duplicate glass from ebay for approx Rs 1500?
Anyone had experience of how the quality of duplicate glass is would be of great help. Thanks a lot. :)
