I have this one and think it is fantastic! http://www.amazon.com/gp/product/B00U6EZC5S/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I always buy from Tech Armor if I can. Great protectors, cheap price. I bought one of their glass ones when I first purchased my GS6 earlier in the year and haven't had an issue yet with it. Crystal clear, super easy installation and a little over $8 and Prime Shipping.
