I have bought twenty plus stocks from Richter. Each one was well dried, good grain flow and well described. Some from Ebay which he sells under the Quaking Aspen seller name and some direct from his website. They are the best Ebay seller for stocks but that is not saying that much. Not every stock they sell is perfect but they are perfect in description and take some of the best photos showing all sides and the end grain with highlights of any potential problem such as burls, checking or grain chipping. I think that Ebay gets many of the stocks leftover from their other sales sites so they tend to be a mix from low grade to very high grade.
I have bought two stocks from Goby and they were as described.
