When I see the phrase "estate sale", I will tend to stay "far" away. Not really a wise marketing statement for any seller. As mentioned, it gives the perception the seller does not know the "true" condition of the item being sold (i.e. other than cosmetically and of course, "it lights up when plugged into the wall.") If a seller does not want to give assurances, then mentioning "estate sale" fits the bill. However, will the seller accept returns? Who pays for your return shipping cost when the item fails to function as expected? Why would a Ham seller not know the "true" condition of an item (a legitimate question which may carry many reasons behind it)? Many things to consider, especially when the seller cannot or does not want to thoroughly test anything listed from the "estate sale". To me, such items for sale hold "minimal" appeal, as I have to assume they may not work and the pricing posted usually assumes they do.
