I guess it comes down the initial point, the buyer should have inspected the machine in person.

However, with interstate deals that's not possible, so we take for granted whatever the seller tells us.
With that in mind, i tend to put on the "i'm buying a piece-o-crap, and i'll need to work on it" thinking cap.
At least i'm not so disappointed when a crap machine arrives 

As we know, pinnies are complex machines, and sellers may describe everything they can see, but electrically, well, anything could paff out without warning.
Naming & blaming a seller publicly can be a good warning for other buyers, but, if the seller was innocent with the knowledge of the machine in question, then why not give benefit of the doubt?

On the other side of the coin, sellers who consistantly sell shyte machines as "near new" should be named, hung and fed to the rats.
