The reason those bows are so expensive is because people will pay it. The manufacturers are only charging what the market will bear.

PS: I will never buy bows or electronics on Ebay. You just don't know what you're getting. It's real easy to mess up a bow and sell it on ebay or unload one that has never been "right". You don't think the Pro Shops sell all the bows that were dry fired at the shop to there customers do you? They don't want to service it later. Unload it on Ebay. Not saying you can't get a good one there, just too big chance your getting somebody elses headache.
