50mm Prime Lens

So my dog ate my favorite lens... after my wife dropped it, I recovered it, my dad dropped it, and it was left outside. I am debating which 50mm prime lens to purchase, though it is hard to go wrong with the f/1.8 lens from Canon for about $100 (aka the "Nifty Fifty"). I have taken some of my best digital photographs with this lens. At this point it's a matter of when, not if, I will replace it.
