Don't get turned off by one or two negative comments. Some buyers are unreasonable and leave negative feedback when they shouldn't. Avoid sellers with little or no feedback and definitely stay away from any that hide their feedback. Paying with a credit card is another way to protect yourself. If the seller doesn't deliver, your credit card company can get your money back for you.
Most sellers take credit card payments now.
However, don't e-mail your credit card information to anyone. Use a service like Billpoint. Most auction sites have such a service. They are in Very Good condition, with no tears or stains. The only difference is that my set had a few pinholes where they had been displayed, and one had a tiny piece missing.
