I'm pretty sure the only good one you can buy is TFWPKY. All the others have to drop or earned through bounties. My personal fav is Timur's Lash. It's impact and range are impressive. Get a great roll, and there isn't anything that can hold a candle to it. But if you could have any of them, I'd prob choose the Hawkawesome. Unfortunately, I've got about 7 months before I can even possibly get it.
