I'm upgrading to either the s4 of the HTC 1. This will be the most I've ever spent on a phone. I tended to be a cheapskate and only buy free or phones < $100. I was wondering whats a good case that will protect the phone from falls? I worried that I will drop the phone and shatter/crack the screen. I seen case prices vary from $8-$50. I was hopping you guys could recommend a good budget case. Will a case protect the screen from cracking if dropped or do I also need a screen protector
