Best model to Screen Part to buy for Nexus 5 screen replacment

Hello, I have cracked my Nexus 5 D821 (and unlike most users just admitted it rather than blame someone else) and would like to know what the best part to purchase for a screen replacement is. The cracks are at the bottom of the phone and extending from a hole in the screen. I can see the red colour of the back plate through the hole. The screen responds fine to touch and the notification light is not damaged. I was wondering what the best part for me to purchase is. I am Australian and thereby do not use American dollars so when speaking about currency please specify which currency you are talking in. My phone is red. I am looking at the $58 USD part here as it look to be good value and easy to install DIY. ( http://www.ebay.com.au/itm/281581984853 )

Any input is most appreciated!

Thanks
