It's probably true to say that most of the serious record dealers have moved to discogs or have their own websites, or other means of selling. Furthermore, there are just too many records that don't warrant being auction items. As a seller listing on eBay is a pain in the arse and then they gouge you every time something sells. Don't get me wrong, eBay is great for buying stuff but as stated earlier it is a jumble sale.
