I like the Safari Tuff quivers, particularly the Arrowmaster. I've tried tons of different quivers over the years, bow quivers to back quivers. The Arrowmaster is the absolute best, most versitile quiver I've ever used for hunting. Easy to hang it on a tree when you get to your stand, fletchings are protected and covered. You can see them at Safarituff.com.
For looks, it's hard to find one that compares to Art Vincent's Cedar Ridge leather quivers--absolutely beautiful, and functional.
