iWrap. Full $20 (19.xx) kit includes front and back screens, sides, home button, even the top and between the buttons, only the bottom is uncovered where the speaker mic and jack are. Lifetime warranty included. Just like zagg except much clearer, no orange peel effect and no solutions/water necessary to apply. I'm very satisfied with it.
You just have to be very careful and exact when applying it. When i was applying mine, i dropped my screen microfiber wipe thingy and it touched the adhesive and ruined the back screen protector  so i got a zagg on the back only. I didnt use the front screen protector provided cuz i like the thinnest and least intrusive display, but if you're worried about drop protection id use it. It's thicker than normal screen protectors but clearer than zaggs. 
Good luck.
