I would go to a place that does only cameras and look at their used stock, people who spend 800$ on a new lenses are the kind of people who will also take good care of it and you can get great deals on used equipment from a place that knows about them. Instead of of a pawn shop that might know noting about it and bought it from a person who may have never payed for it to begin with. Mind if you just want them because you think they are cool and don't intend to use them, I'm sorry I can't help. Please downvote me so I may learn from my mistakes.
