That's true, it's always 'buyer beware' but I was referring to club moderated swap meets.
I think there is a higher level of confidence if you buy from a fellow club member simply because you will see them again. Emails, phone calls, Private Messages, etc from faceless sellers can go ignored. Face to face confrontations and peer pressure tend to make people carefully evaluate their selling practices. Granted, a cheat will always be a cheat, but I think they would be less likely to treat a fellow club member in that manner.
