Gunbroker exists to put potential buys and sellers in contact with one another. For the small fees they charge, I think you are asking rather a lot. You did your homework, and others need to do likewise to protect themselves. If GunBroker starts suspending dealers because of disgruntled customers, they will just go elsewhere. I am not including you in that category, but there are a lot of totally unreasonable and nutty "customers" out there.
