I think the best policy would was suggested by the original poster
For dealers:
1- Clearly announce that you are a dealer
Obviously people do buy equipment based on advise given at Audiogon. I do go to trusted brick and mortar stores for information and purchases. However, I know they are a dealer and are employed to sale their products primarily, which is fine because I can check out other products elsewhere. Some dealers are very honest and helpful here, others are not. I would think trustworthy dealers would be fine with a disclosure policy.
