The location is perfect in Las Vegas because people need money all the time to Gamble. They give away good stuff for nothing. I would never start a pawn shop unless its in Las Vegas.
I agree with securesite, there's people there willing to sell priceless historical relics and antiques for a quick buck. I believe one time a person sold some civil war items for only a couple of hundred dollars =S Ticked me off mainly cuz I'm a U.S. history buff.
I seen it on TV but never much cared for it. It does however teach people how to buy and sell but i personally would never sell at a pawn shop since they will resell it at double or even triple price they payed for it. When you could get the same price if someone else payed for it if they was to sell it.
