If you're planning to hunt out west for mule deer & elk from the ground in rocky, tough terrain, then buy a tight spot or similar. You'll appreciate a good quiver after sliding 100ft down a loose gravel slope with bow in hand, or army crawling across a sage prairie with bow in hand. That's where an expensive quiver shines.
But if you're hunting whitetails from a tree then buy the cheapest quiver that doesn't gorilla grip your arrows. When in stand and need a second arrow in a hurry, you'll appreciate a quiver that you don't need a pry bar to get it. When I'm shopping for a quiver I go to a sporting goods store and try them out. They sell arrows and they sell quivers so try them out like you do shoes. It took me once fumbling to get an arrow out after spining a buck to learn that lesson.
