Been a ham for almost 50 years and have never been ripped off because you need to pay attention to those red flags. Now, would I ever purchase anything from someone with disclaimers such as no returns due to parts swappers. no. Will I ever purchase anything form someone who claims that it worked fine last time he used it, no. Will, I purchase something from someone who claims that his uncle used it and it worked fine before he died, no. Will I ever purchase anything from anyone who stated that I came form a estate sale but he has not tested it, no. Will, I believe anyone who is selling a year old or 20 year old equipment that he claims is brand new and only took it out of the box to take the picture, no. These guys believe in PT Barnum phrase that there's a sucker born every minute. Unless is a bonafide business with written return policies, you buy it, you own it.
