I only use PayPal G&S, and try to get a feeling of who I'm dealing with, and believe if it seems too good to be true, it probably is. So far, so good, both buying and selling. Here on the West coast, there is a weekend swap that has been running on 7.240 for more than 40 years. Nobody is trying to get rich, just sort of trading gear around. It's my go to for buying and selling.
