Not only an exhaustive supply of classic games, but also some really good customer service. We went into Gamers Paradise to satisfy my curiosity, and the owner asked if there was anything in particular I was looking for. I asked for a relatively obscure piece of hardware, fairly confident he wouldn't have it. He didn't, but he then went about searching for various places I could find it, and helpful hints on the best way to have it shipped to me. I was really impressed with his determination to find a solution and get the customer what they wanted.
Here is a business well worth supporting.
