What repair kit should I buy for an iPhone 4s from Sprint?

I shattered my iPhone 4s screen from Sprint. I want to buy a new repair kit but there are mixed reviews on all of the products on Amazon. I also need to know which one will fit and work well. Anything from any personal experience? Anything would help.
