I forget where you are located, but if you make it to Compton, or any of the other major regional shoots, there are usually a couple guys who regularly set up booths who deal in good used bows. not just collecticles or high end customs. Of course they are buying low and marking up, (and usually you can talk them down a little on their tagged price, especially if you wait until they are about to pack up on Sunday); but their general pricing can give you a better idea of "real world" values.
